[Gtk-sharp-list] Still can't show config dialog, but can show anything else

[Aaron Oxford]

Hi again,

As promised, here is a modified test program demonstrating the 
timer/dialog lockup. The expected behaviour is to see the main window 
pop up, then be obscured by a dialog saying 'testing testing 1 2 3', 
which in turn is partially obscured by a blank dialog. The app will 
then freeze, and after a while Windows will unblock it and let you kill it.

The desired behaviour is to see the second dialog, full of 'the quick 
brown fox jumped over the lazy dog', and to be able to close all 
three windows and exit the program.

Hope you're enjoying your weekend.

Aaron.
