to be honest: I don't have the slightest idea. This is the first multi 
threaded gtkmm program I came across. Looks like the infrastructure is 
there at last ...

My guess: The glib main loop detects whether your process creates new 
paint requests every N microseconds. If it still does, the redraw is 
held. Perhaps something around "while event_pending do process_event" is 
needed regularly in your work thread. Try to ask on the gtkmm list or 
the gtk/glib list, this problem is not C++ specific.

And please: tell me if you know what the problem was.

no problem for me. If you had zipped and attached it, it'd have been 
more difficult for me to read it (one more step) ... I'm ambigious about 
attachments vs. inline.
