Hi I have the same problem as mentioned by Thorsten a few weeks ago. However, I am running NT 4.0 sp6a. So, it has nothing to do with XP.
When I am running XFree in multiwindow mode (clipboard enabled), and launch xemacs on my remote debian machine, Xwin crashes (I can give you the memory location, but that won't be very helpful I guess). However, when I do not use multiwindow, everything is fine. $ cygcheck -c XFree86-xserv Cygwin Package Information Package Version XFree86-xserv 4.3.0-5 My cygwin setup was last updated around 30th of August (cygwin dll 1.3.22-1) because I'm a bit reluctant to go to the new 64 bit stuff before lots of other people have tried it....
