Hi, This was also happening to me on XP, randomly, on closing any old windows (fonts in the Control Panel was my test case!). I've been chasing this one, on and off, for a few days with no luck!. Fixed, I think, with the latest snapshot cygwin1.dll (6th May). I'll test it to death now and see if it breaks (xwin-gl-6.7.8 in multiwindow on XPsp1)
