Splash screen moves up before closing

In C# I am having a problem with the splash screen. When it is time to close and the main Form1 appears, it moves over to the upper right corner of Form1. It then disappears. I have never had this occur before and have just about run out of ideas to fix it. I want the splash screen to disappear in the center screen and not move over to the upper corner of the opening Form1. Here is the code:

public Form1() {
    Splash mySplash = new Splash();
    mySplash.TotalValue = 7; //or however many steps you must complete
    mySplash.Show();
    mySplash.Update();
    InitializeComponent();

    //--<begin>--------------
    this.Hide();
    this.WindowState = FormWindowState.Normal;
    mySplash.Progress++;
    printDoc.PrintPage += new PrintPageEventHandler(printDoc_PrintPage);
    printBOM.PrintPage += new PrintPageEventHandler(printBOM_PrintPage);
    printList.PrintPage += new PrintPageEventHandler(printList_PrintPage);
    mySplash.Progress++;

    // using old Kodak Imaging OCX !
    axImgEdit1.Image = "\\\\Netstore\\eng_share\\EView\\BOB-eView9.tif";
    axImgEdit1.DisplayScaleAlgorithm = 
        ImgeditLibCtl.DisplayScaleConstants.wiScaleOptimize;
    axImgEdit1.FitTo(0);
    axImgEdit1.Display();
    mySplash.Progress++;

    List<Win32_Printer> printerList = Win32_Printer.GetList();
    int i = 0;
    foreach (Win32_Printer printer in printerList) {
        prnName = printer.Name;
        prnPort = printer.PortName;
        prnDriver = printer.DriverName;

        if (i == 0) {
            prnNameString = prnName;
            prnDriverString = prnDriver;
            prnPortString = prnPort;
        }

        else {
            prnNameString += "," + prnName;
            prnDriverString += "," + prnDriver;
            prnPortString += "," + prnPort;
        }

        i++;
    }

I see from the multithreading stuff in splash that it looks like you tried to make the splash screen operate more smoothly and probably ran into the error about updating form properties from a different thread than the one that created it.
Ways around that:
- Invoke (looks like complicated code but really not that bad)
- 250ms timer in the splash thread that takes commands from instance variables / properties (hackish)

So it must be that the progress bar manages to update itself anyway. You could alway put in a me.refresh in the progress setter if you're having trouble with that. Or doevents after updating the pb, which really should only be used when there is any visible form with no controls that can raise events (e.g., click) which you might be handling on it, as that will cause reentrancy.

But that's not what you asked. Sorry. To fix that w/o re-writing, add this code before the close/dispose of the splash

MySplash.Visible = False
System.Windows.Forms.Application.DoEvents

Forgive me if I can't test it to prove it, I'm lacking a simplest - reduced-case screnario which manifests the problem to load up and test with (tip - always do that when posting code, 50% of the time you find the bug doing it, the other 50% you'll actually get people giving you answers as many won't read past 2 screens of code). I am also not promising that won't cause problems with the app appearing under another window on the screen, but you didn't ask about that either ;-)
