Hi again !
Despite the many e-mails and suggestions I received, nothing has solved my problem so
far.
So, I stripped down my program to some essentials to show you the problem I am running
into:
The script below does nothing, but consumes 95% of my CPU !
If I comment out the line
self.area.modify_font(font_desc)
Then the CPU usage drops to the expected 0.1%
Can anybody find the reason ?
Once again the pygtk and python version I am using on my redhat 9.0 box are the
following
