If you think it's clipboard related, try running with -noclipboard and 
see if that fixes it. Downside is, you lose all clipboard functionality...

BTW, what do you use x11 for? Other than the odd gnuplot session, I've 
not needed an X server since switching from xterm to mintty (which just 
became the official cygwin terminal). If a similar situation applies to 
you, you could temporarily switch to mintty while doing the above 
experiment and still be able to use clipboard in the meantime.

Finally, I've never used a multi-monitor setup myself, but according to 
the XWin man page you should specify the -multimonitors option since you 
apparently (really??) don't run in -multiwindow mode. Or maybe the man 
page is just out of date and -multiwindow is the default now, in which 
case multiple monitor support comes for free.
