(Solved/Void) Form Start location will not update/renew after changing form size

Hi All, never thought I would be the one posting a question but this one is baffling me.

I set the form startup location to centre on my 2nd monitor (dual) last week.

This week I increased the form height to add more function but the form insists on its starting location being that of the old form.

Both Monitors are 1280 x 1024

The code for setting the location is as follows:

 Dim screen As Screen

  screen = screen.AllScreens(1)

  Me.StartPosition = FormStartPosition.Manual

  Me.Location = New System.Drawing.Point((((1280 / 2) - (Me.Width / 2)) + 1280), ((1280 / 2) - (Me.Height / 2)))

This worked just fine before I changed the form height.  However, once the form size changed, the location did not update as it should have with the x,y co-ordinates still acting as if the form was the old size.

I also tried to change the location manually by entering in the exact x,y values but the form starts in the correct location and then a split second later moves back to the old incorrect location.

Is there something I am not doing to flush the old values?

No edit option. Additional info: I am on Windows 7 32bit and use Visual Studio 2005.

What happens if you use:

Me.StartPosition = FormStartPosition.CenterScreen

rather than centering the form manually?

Tried that one, again it starts in the correct (center screen) position but after a split second it reverts back to the old incorrect position.

I'm away from the PC at the moment but I'd nearly create a new form and copy over all objects and code to see if that one works.

Feel like a tard. Must have been sitting in front of the screen for too long. Got home and fixed the problem within a minute of looking at it! Had put bit of code in the 'form closing' event of another form a long time ago and forgotten all about it. Was setting the new form to open in the closing form's location. Initially both forms were the same size so problem only surfaced when I changed the size of one of them. Duh! Sorry to waste your time guys.
