frozen GUI!!! urgent help required!

[RevX gmx at]

Hello all,

I've the following situation in/with my GUI (actually
I'm using Gtk--, but that shouldn't matter because
Gtk-- is only a wrapper for Gtk+):
A checkbutton gets pressed and calculations
begin (involving retrieving of images from a
video camera and processing them). And
at this moment the GUI is frozen, no buttons
are clickable anymore and the window isn't
redrawn when temporary overlapped by other
windows. It looks like as if everything is frozen.

So, what is going wrong??? Does the GUI of
Gtk+ not run parallel to the calculations to fetch
X events or is it a fault I just don't see?!
I hope someone can help me (soon).
Thanks for helping in advance.

Cheers,
Michael.
