Appreciate the time you've taken to respond. Yes, I'm new to all of this. Had toyed with the thread idea but wanted learned thoughts from people the time BEFORE I committed the time to studying the various options.
I'll certainly read what you referenced. Your response made good sense. Thanks so much.

The latter does drawing, and rereshing. That is why the program behaves as it does. > > The window outline appears but no inside until after 5 sec when the full > window takes shape my name then appears. > > What I want is the full window appearing at the beginning and then 5 sec > later my name appears. > > Make sense? What you want is clear to all, but the way you want it, is not going to fly. You cannot block in the thread of control that does 'gtk.main()' (well, you can, but it does not do what you want). There are 2 solutions to this: 1. start another thread to do your processing, and have it coummunicate with the gtk.main() thread to update the window. 2. do everything event-based. Instead of sleeping, start a timer, and attach 'print name' to the handler that gets called when it times out. I would recommend that you look at the tutorial (http://pygtk.org/pygtk2tutorial/index.html), in particular chappters 19, 20, and 24. The latter is an example. To understand those chapters you may want to do the entire tutorial. Since you seem new to event-based programming, it won't be wasted time, I think.
