could you use strace to know exactly what syscall is being called and which arguments and try to understand why it hangs... it might be an X error, since it's the X call that hangs... maybe there's something special to do to avoid it (always think that we're probably not the first ones to encounter that error...), maybe your X server needs an upgrade or a patch... Also, as Phil knows, that part of the code with the displayproc hooked is 100% unnecessary, or worse, it's slows us down.. so maybe it's not even necessary, and it can be removed right now.. I know Phil is working on tkcximage lately, so maybe he'll think about it and fix or remove that part of the code.

p.s.: a solution someone on #tcl gave is to bundle each image in a label, and do IsMapped on that label.. for anigifs... this will work for scrolled chatwindows...

when i remove the whole fix "XGetImage that happens with Tcl/Tk before
8.4.9 that caused a BadMatch" stuff it no longer seems to hang..
So any c-coder that wants to fix this?
