[Gtk-sharp-list] Xlib: unexpected async reply (sequence 0x27)!

[Mark Lee]

I'm a beginner in both GTK and C# I'm afraid so please bare with me.
I've got a client application that's got a listener thread that receives
messages. As the messages are received events are triggered in the
parent thread and these messages are displayed on the command line. I'm
trying to now write a GTK interface but whenever I try to create a
window I get the following error:

Xlib: unexpected async reply (sequence 0x27)!

It's only when I call Show() or ShowAll() that I get this error. If I
create and display the window before any message processing and just
populate the contents of the window as messages arrive I don't get the
problem.

Am I missing something? Thanks,

Mark
