Ooops again, I forgot to include overlap of buttons exclusion. Just do an intersect check if true then hit on placeBtnRandom command again.


   put the width of btn pbtnName into bW
   put the height of btn pbtnName into bH
   put the width of this stack into sW
   put the height of this stack into sH
   put random(sW-bW) into tX
   put random(sH-bH) into ty
   set the loc of btn pbtnName to bW/2+ tx, bH/2 + ty
   
end placeBtnRandom

It's not a huge area to work with, but the controls are not too big. The conditions are that the controls cannot intersect (overlap) and they have to be completely visible within the given area (not partially off-screen).
