Has anyone else noticed that Uvision V2.39 has a bug when using workbook mode at high screen resolutions (greater than 1024x768)? The workbook tabs at the bottom of the windows will become erratic, disappear, not refresh properly, etc. Keil has said this is not a bug....but it obviously is. V2.36 does not have this problem at high screen resolutions, so they did something from V2.36 - V2.39 to cause this.
"Keil has said this is not a bug...." How did they justify the behaviour then? Stefan
"Has anyone else noticed that Uvision V2.39 has a bug when using workbook mode at high screen resolutions (greater than 1024x768)?" No. I have it working fine at 1280x1024 on both NT4 and XP-Pro. Time to check your video drivers?
"How did they justify the behaviour then?" They said it was my video card/driver. If that's so, then why does V2.36 work fine with my video card? This "problem/bug" is not only isolated to my computer/video card. The same problem exists on 3 different computers, all with different video cards and all of them worked fine with V2.36...but none of them will work with V2.39?? I have chosen not to upgrade my version, as the workbook mode is extremely useful for me. But I will have to relent sooner or later and upgrade. I can only hope to find a solution to this before that time comes. Thanks, Brian
I should also note that all systems are running Win98Se, if that matters.
I just tried a cursory test using Windows XP and uVision2 V2.40. Everything seems OK. I'm using a Matrox 3-head video adapter with a video resolution of 3840x1024 (yes, 3840). Windows 95 and Windows 98 were plagued with unstable video drivers that appeared to work for most applications but not for others. What do you do to make the tabs get messed up? If you can give me a list of stuff to try (preferably with one of the exammmple projects) I can see what happens on my machine. Jon
I've had similar problems with Keil's IDE, i.e. various lame behavior from the GUI, and I'm running Win2K. One example: the memory window, which I've set to reside in the main frame of the overall IDE window, keeps resizing itself throughout the course of a day, slowly growing at the lower right corner. And, I also experienced them trying to foist responsibility onto the video card, drivers, OS, other running programs, phase of the moon, etc. The simple fact is that a) the tool has numerous bugs that they're apparently ill equipped to root out, and b) they have a very poor quality / customer service ethic, and don't want to own up to the situation.
All you have to do is enable Workbook mode in the view options, then maximize the UVision window. (I also have the status bar enabled.) The workbook buttons will be gone, the screen will not be refreshed properly and all other kinds of weird things happen. If you then manually resize your window so it's smaller, the buttons will come back at a certain point. It is worse if you have the Output window enabled and docked to the bottom of the screen (full width). If you grab the resize corner and drag the window to full screen, you will start to see the status bar and workbook buttons get distorted as you approach full screen. It's like the window size parameters do not take into account the extra space the workbook buttons occupy when enabled. I have confirmed that this also occurs with WinXP. Thank, Brian
All of this works perfectly for me! It even works if I stretch uVision over 2 monitors at different resolutions! (though that naturally looks a bit funny!!)
"The simple fact is that a) the tool has numerous bugs that they're apparently ill equipped to root out, and b) they have a very poor quality / customer service ethic, and don't want to own up to the situation." This seems a bit harsh to me. I have found Keil to be very quick to fix compiler/linker bugs but I do find it irritating that they don't keep a list of known bugs in the current version on the website. I suspect that quite a lot of their customers waste quite a lot of time tracking down known but undocumented bugs. Stefan
Earlier I stated V2.39 has the problem. I meant V2.40. Sorry, I got the 2.39 from reading the release notes which state 2.39 is the latest. Nevertheless, something changed from V2.36 to V2.40 which has affected the workbook mode on all systems we have here. It would be nice if changes were documented between versions, especially bugs. Why was V2.36 upgraded? What were the changes? And which one of those changes created this problem? As I stated earlier, my video drivers and all other hardware worked fine with V2.36, the only change in this whole equation is the UVision software. There is nothing special I have to do in order to duplicate this problem....only maximize the window with the workbook buttons on. That's it. My screen setup is as follows: - Status Bar ON - File toolbar ON - Build toolbar ON - Output window open and stretched full width across bottom of screen, about 2 inches high - Project window open to left of screen about 2 inches wide, on top of output window - The rest of screen for viewing files Even with no files open, selecting Workbook mode will change the border around the files window as it resizes it to include the tabs on the bottom, but it doesn't refresh properly. Sometimes sections of the desktop can be seen through the Uvision window. I appreciate you guys trying to help...someone else has to have this problem. Brian
OK. I just tried everything you suggested on another 1280x1024 and everything works well.
Here are a few other questions:
OK, I got it working on one computer! I did as you suggested, Jon, and lowered the graphics acceleration one notch. Sorry I didn't try this simple step earlier, but I didn't since it worked with V2.36 at full acceleration. Why it works with 2.36 and not 2.40 is still a mystery....but is inconsequential at this point. I will try this on all our systems and am pretty sure it will solve this issue. I'll search for upgraded drivers and see if I can then increase the graphics acceleration back up to full. Thank you! Much appreciated, Brian
OK. Did that get things working on all of your PCs? If so, what video card were you using so the rest of us can avoid it. Jon
I got all the computers working now. The funny thing is I never installed the new version on my computer because of the problem, but when I did upgrade my version yesterday...I found that I didn't even have that problem on my computer! I guess it's cause I always search for updated drivers on a regular basis. But 2 computers here only work if the graphics acceleration is set down one notch (or if screen resolution is set to 1024x768 or less). Computer 1: - ATI XPERT@PLAY AGP 2X video card - Driver 4.11.2628 (Trying to update this driver only caused computer to lock up when booting) Computer 2: - 3D Force B23 Plus NVIDIA RIVA TNT2 Model 64 - Still need to upgrade to newest driver released 12/9/2003 I haven't been able to play with Computer 2 yet...people get mad when you try to mess with their computer while they're using it, LOL.
