[Gtk-sharp-list] Gtk.DrawingArea not thread-agnostic on Win32?

[Cody Russell]

Yeah, GTK's Win32 backend won't play nice with multithreaded apps right
now.  This is something I'm wanting to work on and fix at some point
when I find some time to do it.  Would you mind making a simple test
program like the one you just described and give it to me to help test
with?
