Workbook mode not working at high screen resolutions

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.

  • 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.

    And people were throwing mud at Keil... ;-)

  • It's a bit unlikely that two completely different drivers for two completely different cards happen to show exactly the same bug in exactly the same set of circumsdances. Sounds more like something not quite right with uvision to me.

  • No, the mud was thrown when Keil added something to V2.40 which created this "problem"... which was not evident in V2.36. ;-)

    I have nothing against Keil and am very happy with their products and continuous improvements.

    People make mistakes, I just want to find to a way to fix them...and I have thanks to Jon.

    Ah, but Keil software is *expensive* unlike video drivers supplied with far-eastern video cards. I guess people expect more.

    Well, I'm not sure just WHAT we could have done to uVision to create the problem. We use Microsoft Visual C++ and the only things I can find that we changed there with regard to windows or dialogs is that we added more descriptive text on the left side of windows that dock. This was done using an MFC routine -- uVision doesn't manipulate the display directly, it uses MFC library calls to do stuff like that.

    So, I contacted a buddy of mine who is one of the software developers at Microsoft and described the problem. His first question was ... does this involve an ATI video card...

    Here were his comments.

    • If changing the hardware acceleration level fixes the problem, then the problems is not in MFC.
    • The Microsoft video driver for ATI video cards is well tested and stable. In fact, it's probably more stable than the ATI driver. You may want to use the Microsoft driver (if there is one for 98se).
    • Run the card at 60Hz and see if this solves the problem.
    As for the Riva TNT card, we have several of these here and they all work beautifully.

    One thing to consider for both cards is that the problem only shows up when you increase the resolution. Increased resolution means more memory to access. And, the memory has to be accesses faster (because the screen refresh stays the same). So, flaky (or slow) video memory could be causing this problem. Setting the refresh rate slower may solve the problem -- it may also cause siezures (I have problems with refresh rates below about 72Hz).

    Hopefully, some of these comments help you get up and running.
