David, thanks for your help. I changed the startxwin.bat to: start /B c:\apps\cygwin\bin\bash --login c:\apps\cygwin\usr\X11R6\bin\startxwin.sh This is a good idea in general, because it eliminates the maintenance for two files (.sh and .bat). I still have some trouble with changing the theme, but icewm is working. Rüdiger Bodack >
