WireShark (was: Spurious bad X_ChangeProperty and MappingNotify)

[Pat Kane]

Peter,

Thanks for the info.

 I  am currently trying to debug a problem that only  happens
when a user is running two MS word programs on top of Wine,
with my local   Xorg server.

 A copy & paste between the two MS windows mostly works  ...
but once in a while will get confused.

How hard would it be for me to describe my  small  local X extension
in XCB format and get Wireshark to grok it?

I esp. need to track the  XConvertSelection   process.

Pat
