An hour ago I installed the last version of this software, then I opened my project and added some files with extension "*.h" I opened them as "C Files", then when trying to close them one of them closed, but I cannot close the others (I opened three of them). I already re-started my computer but I just can't get these files off my project. I right click the mouse over the file select "remove filename.h" and asks If I am sure I want to remove it when I select yes, it does nothing!.
I was able to remove the files the way Andrew indicated, with the "delete" key. This way worked properly. Luis A. Macias.
OK, We have confirmed this problem and it will be corrected in the next C51 release. Jon
Looks like C166 needs the fix, too: http://www.keil.com/forum/msgpage.asp?MsgID=1918 Will the ESC key be fixed, too: http://www.keil.com/forum/msgpage.asp?MsgID=1901
C51, C251, C166 all have this problem and are corrected in the next release. Just added the ESC problem to the list. Jon
