Das "Verstecken" der Gui lässt sich mit _WinAPI_CombineRgn durchführen. Das ist alles etwas sperrig und deshalb habe ich das mal in eine UDF verpackt.
Mit Aufruf der Funktion _GuiBGInvisible wird eine Ctrl-ID oder ein Array von IDs übergeben. Diese Ctrl werden dann ohne Gui - also frei schwebend - angezeigt.
Optional kann eine Funktion übergeben werden, die anhand der ID das entsprechende Ctrl von der Anzeige ausschließt. Die Funktion muss als einzigen Parameter die $ID führen und True/False (ni. anzeigen / anzeigen) zurück geben.
