There is for sure something wrong with screen and window positions.
I have been looking at the issue and i wonder is there is some mix up with
what top-level window is to screen.

If i use code like this..

Public Sub Form_Move()

  Print Me.Left, Mouse.ScreenX, Mouse.X
  Print Me.Top, Mouse.ScreenY, Mouse.Y

End

Public Sub Form_MouseDown()

  Form_Move  ' I have to use this as Form_Move() event only triggers when
form is opening, one is is opened and i move the form it does not trigger

End

I get the following results...

When program opens Form_Resize triggers twice, first Me.Left and Me.Top are
384, 194 then it jumps to 26, 23

The windows ACTUAL position seems to be 0,0 to the screen available X and Y
(far left and below the top panel)
Then moving the window and clicking it i get the following...

Mouse.ScreenX and Mouse.ScreenY are reporting Mouse.X and Mouse.Y relative
to the window not the screen.

Me.X and Me.Y are always 26, 23 no matter where i move the window to.  (and
as mentioned Form_Move() does not even trigger)

It's as if gambas is mistaking the top level window for the screen or
something?

I do not begin to understand the depths of the problem with all that but I
offer my observations Banoit that i think point to a possible issue.
