GtkButton does not respond to mouse click

- Date: Tue, 23 Jan 2007 17:07:48 +0100
Hi all,
I wonder how to post to this mailing list. I sent a question two
times now, but neither I received my original question nor any
answer...
So here is, for the third time, my question:
I have the following problem within my GTK program:
I click a button - this triggers the generation of a new window.
When I want to click the button again it does not recognize the
click unless I move the mouse cursor off the button. The keyboard
still has the focus on the button.
This only happens under the WIN32 environment; when I compile under
Linux everything works. I attached the sources together with the
Makefiles. I use MinGW under Windows.
Thanks for the help,
Johannes
