Thanx for the help all. I still have the problem, though. I uninstalled my NetScreen VNC. I also turned off AVG.
Let me give more details. The app that I am running is just the default form that was created automatically. There are no controls on the form.

As an experiment, I created a C# app with just one form and no controls. This app/window comes up immediately, no delay like the managed C++ app does.

I am running XP Pro with SP2.

TIA
