I like both approaches (CreateEvent and CreateMutex) more than creating a dummy window because I think there is less of a chance for any unexpected behavior from the "hidden" window (since it will show up in the forms collection). However, both of them suffer from the same limitation of not being able to identify the running apps current window name. If you change the title of your app, FindWin won't find it anymore. The CreateMutex approach assumes the window name won't change. So, I think I'd stay with the current set of code we've got (unless you see another way around this). BTW - get some sleep ;-)
