Bruce STEERS reported a new bug.

Summary
-------

Form.Border and Form.Top

Type             : Bug
Priority         : Medium
Gambas version   : Unknown
Product          : Unknown


Description
-----------

I'm getting a headache with a program.

It does the following....
Has an option to show/hide the window title bar (Border)
I also uses Settings.Read() / Write() to save/restore window position.

Gambas is not giving the correct top position in some cases.

the window "Looks" fine with the postion and size before saving the data but on program restert the postion is wrong.

I'll attach a very simple test app that saves/restores position and has a checkbox to turn border off or on.

Problem is hard to explain.
A good test with the following app is to run it, show the border , hide the border,  then close program and open again.
It will be placed the titlebar height too high
