When FVWM hangs on a Firefox page with an HTML <INPUT> widget (one must actually enter text), the backtrace is:
#0 0x00e66402 in __kernel_vsyscall () #1 0x0067a7eb in poll () from /lib/libc.so.6 #2 0x007b0aa9 in ?? () from /usr/lib/libX11.so.6 #3 0x007b0e8f in _XRead () from /usr/lib/libX11.so.6 #4 0x007b1854 in _XReply () from /usr/lib/libX11.so.6 #5 0x007914a0 in XGetGeometry () from /usr/lib/libX11.so.6 #6 0x0806c371 in HandlePropertyNotify (ea=0xbfdfceb4) at events.c:3314 #7 0x0806b619 in dispatch_event (e=0xbfdfcee4) at events.c:4138 #8 0x0806bcff in HandleEvents () at events.c:4182 #9 0x0808d01a in main (argc=3, argv=0xbfdfd994) at fvwm.c:2591 I would guess that FVWM is trying to get geometry information from the X11 server, which never returns. Does this necessarily mean that this is an X11 problem? Correspondence
