Hi,
Here's the XWin.log file. It doesn't seem to mention anything at all
regarding closing of windows failing, yet for sure I tried several times,
several windows, and it didn't work.
It seems also that when I minimize a window, and restore it, the only way to
get key-events working again is hitting the 'enter' key one or more times.
<<XWin.log>>
But.... now I restarted X, first without the -clipboard option and then
again with -clipboard option, and can't reproduce the problem. I'm 99% sure
though that I *did* restart X since I first observed this problem.
