Hi.
I developed a GUI program using microwindows for arm-linux system. Linux kernel number was 2.4.5.
Of course, it worked very well.
However, I found a big problem, while I am upgrading linux kernel to 2.4.19.
When I press "Ctrl+C" to cancel my GUI program, my program crashes with the following error messages.
The same thing happens when I run "ps" to see the process status.
Other programs except microwindows releated program are going well.
Only my gui program and microwindows examples have problems.
Does anybody know about this problem ?
