If you are just using a Glib.Timeout it won't work for a single threaded
app unless you occasionally release to the event loop.
You'd have to change your processing to periodically pause - that really
is all up to whatever processing you are doing. If it is an iteration
you should make sure you run the message queue every X number of loops.
Are you running your processing in an Idle handler?
Or you could do something of the following pattern:
void LongComputation ()
{
while (!done){
ComputationChunk ();
// Flush pending events to keep the GUI reponsive
while (Gtk.Application.EventsPending ())
Gtk.Application.RunIteration ();
}
}

This makes sure all the pending events are processed between chunks of your
long computation.
