Hi! I've had similar problems on amd64... The solution for me was to upgrade fvwm. If you are running fvwm on 64-bit architectures, you might get hit by bug 318504, resulting in exactly this kind of problem.
The solution is to upgrade to the version of fvwm in unstable. / Anders -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
