>What I can tell you is that you are getting bitten by the Windows event model. Because in this case the order things are happening in is out of your control.

Right you are! Did you see in another posting that I found my problem? It was due to the fact that I no longer had any enabled controls on the form. Since no control could receive focus, the form GotFocus() event would not fire.

I decided to leave things that way and added a call to GotFocus() at the end of the Activate method. Works fine.

Thanks for your suggestions.
