comment:
:I was using a program called ferret, graphics display software. I tried to capture screen by taking a screen shot of the graphs displayed!
:problem occurs when I take the mouse to the right edge of the screen while selecting an area of the screen to take a screen shot...
:suddenly the xwindows gets crashed with all zig-zag lines on the screen.
:
:The problem is solved only by rebooting the system. This was found only when I use the latest kernel of fedora 15
:in previous versions the problem did not occur.
