The problem is not that there is no X11-forwarding. For example, gv from the
Linux remote host produces the correct display on the cygwin X-server.
Similarly, xdvi and even netscape also work. However, if I try to run ical, a
linux calendar program, I get the following error message:
X Error of failed request: BadAtom (invalid Atom parameter)
Major opcode of failed request: 18 (X_ChangeProperty)
Atom id in failed request: 0x105
Serial number of failed request: 13
Current serial number in output stream: 16
