My friend and I were playing around with Windows 2.0.3 by running a whole bunch of programs in different windows. One of the programs was a little C program that just infinite looped around printing a message. The trouble was when we tried to stop Windows. When we tried to exit, Windows said that the program was still active and that we couldn't exit. OK - then we tried to close it, but we couldn't, because it was still active. We tried issuing Ctrl-Breaks and Ctrl-C's to the program, but it didn't work. Eventually, we just rebooted out of Windows. Does anyone know any way to stop a program in an infinite loop in Windows? This seems like a feature that should be added more than a bug, but it is very irritating... --------------------------------------------------- Erik Talvola laba-5ac@widow.berkeley.edu "I don't impress easy." -- Jesse "The Body" Ventura ---------------------------------------------------

Eventually, we just rebooted out of Windows. This is a problem inherent to Windows, and it is the programmer's responsibility to avoid these situations. The program which is currently executing processes all keystrokes and mouse commands, ignoring those which are not its own. There are supposed to be ways for the programmer to work around this. Interestingly enough, the Presentation Manager under OS/2 will have the same problem -- the foreground application can completely lock out the keyboard and mouse (see the March 1988 issue of Microsoft Systems Journal).
