Form resizing itself when using code to drag form around

Hi,
    Using VB.NET 2005 and I have a form that I want to be able to drag around by clicking anywhere in the form window. I achieve this by using the below code that has been posted on this site several times. The problem is: after I add this code to a form any time I make changes in the code for the form and then switch back to the design view of that form the form is resizing itself to a smaller size. So if my form size is (453, 200) , after making some changes and going back into the design view the form will all of a sudden be (449, 196).  This keeps happening over and over, the form keeps getting smaller ! So I am constantly having to change the size of the form back and move the controls around again to reposition them. Any idea why this is happening ? Is there a way to prevent this ?  Any help would be greatly appreciated ! Thanks !

Code:
    Const WM_NCHITTEST As Integer = &H84
    Const HTCLIENT As Integer = &H1
    Const HTCAPTION As Integer = &H2
    Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)
        Select Case m.Msg
            Case WM_NCHITTEST
                MyBase.WndProc(m)
                If m.Result.ToInt32 = HTCLIENT Then m.Result = IntPtr.op_Explicit(HTCAPTION)
            Case Else
                MyBase.WndProc(m)
        End Select
    End Sub

I think you want to check if your in designmode before executing the code

if not me.designmode then...

The resizing is not happening when I execute the code. It is happening while I am still working on and designing the code/form.

So if you remove the code it doesnt resize in design? Is this a usercontrol?

Actually, I just tried Removing the code out of my form, and it is still doing it. Why would my form be making itself smaller all the time?  Its just a standard form with a couple of buttons on it.  Any time I make a change to the code of the form, and switch back to the design view of the form, the form size is getting smaller.  This makes no sense.

Try creating a NEW project with just ONE form on it.  Does the problem persist?

If it is only happening on one project/form then it is something local to that project.  It is either "corrupt" or possibly it has a third party control on it?
