Changing Gui Resize option also changes window size

[think]

Changing Resize option also changes the window size/margin - is there a way to avoid this?
Run the script and press Alt+X to see the unwanted effect.

Code: Select all

gui, margin, 20, 20
gui, add, Edit, w300 h300, press Alt - x
gui, show
return

!x::
if s
   Gui -Resize
else
   Gui +Resize
s:=s?0:1
return

[think]

Any idea?
