Splash Screen Fade app causing main app to flutter.

[BillZondlo]

Can someone look at this and tell me why, when I call this from my main app,
it displays fine (fades form in and out) but then before my main app
displays, I see other dialog boxes flash monentarily on the screen and this
delays the main app display?

Here is the fade which I compile to a dll and call from my main app:

I think I found the problem.

Instead of using this line: SplashScreenBas ic.Splash.Activ eForm.Close();

I replaced it with: this.Close();

And it seems to work fine.

Thanks for any trouble.
