Hmm, 
    seems like you're hijacking the main loop somewhere, you
got a `while (42) { /* code body */ }' lying around in your code ?

If its absolutely nescisary to implement the main program loop yourself;
you can call:
    `while (gtk_events_pending()) gtk_main_iteration_do (FALSE);' once
every loop.

Just a guess, OTOH maybe there is something wrong with your X server 
installation (if your not recieving expose events or are unable to queue them).
