How to hold a stack in the background?

[Reinhold Venzl-Schubert]

Hi!

with the following script I go from stack "A" to stack "B" und back  
again. Thereby for a short time stack B gets in the foreground and  
return to the background like a flash. It is not necessary and annoys  
me.

How can I oppress this switch and hold stack "B" in the background?

on mouseUp
   go stack "A"
   set the threeD of img anything to false
   set the ShowBorder of img Auswahlmerker to true
   go stack "B"
end mouseUp
