I recently upgraded to Cygwin 1.5.7(0.109/3/2), including XWin release 4.3.0.56 installed from XFree86-bin-4.3.0-16.tar.bz2
Now when I try to run one particular remote X application (my MUA) I get this error: X Error of failed request: BadAtom (invalid Atom parameter) Major opcode of failed request: 18 (X_ChangeProperty) Atom id in failed request: 0xee Serial number of failed request: 12 Current serial number in output stream: 15 The remote (linux) machine has not had its sshd config changed since 2002. It has "X11Forwarding yes", and used to work fine. If I ssh -X into the machine, DISPLAY is set to localhost:10.0 The MUA runs fine on the Linux machine which I am connecting to with ssh. xmessage and other X applications I've tried also work okay. The MUA is Postilion (a Tk/Tcl application built from the TkRat MUA, but with the Nextstep Mail program's look and feel). Other Tk applications work okay. There's nothing odd in /tmp/XWin.log. Any suggestions? luke
