Position of screen elements: In my GuiXT script I use an offset command in order to define the position of additional pushbuttons:
     Offset (23,95)
     Pushbutton (0,0) ...
     Pushbutton (0,40) ...
Unfortunately, depending on the screen resolution, the offset varies so that the buttons are wrongly placed. How can I avoid this?

In such cases it is better to use symbolic offsets instead of numerical coordinates. For example:

Offset S[tabstrip_xxx]+(3,95)
