[pygame] graphics freeze when mouse click occurs on windows

["Alexander Duesel" <Alexander.Duesel@xxxxxxxxxxxxxxxx>]

Hi,

I am working with a neat pygame application which was 
developed on Linux. Unfortunately I do only have Windows 
running on my laptop and there is a little problem:

The application is controlled only using keys - no mouse 
is needed. As soon as a mouse click occurs or the 
application window looses otherwise focus the graphics of 
the application freezes.

Could this be a problem which can be solved without deeper 
understanding of pygame/sdl? Or is this a common problem? 
I understand much of the python code but do not know about 
pygame/sdl. 

Thank you in advance
Alex
