When first starting a form I have this:

Form.PageFrame.Top = 150
Form.PageFrame.Height = 173
Form.PageFrame.BorderWidth = 1
Form.CommandButton.Top = 326

After I resize the form I have this:

Form.PageFrame.Top = 283
Form.PageFrame.Height = 326
Form.PageFrame.BorderWidth = 1
Form.CommandButton.Top = 615

But the PageFrame is covering 1/3 of the button.

What else is involved in the PageFrame.Height?

TIA
