Hi Devin,
I am with Roger on this.
here is a little code snippet that does constrain the aspect after resizing
-----------------------------------------------------------
on resizeStack pNewWidth, pNewHeight, pOldWidth, pOldHeight
-- block repeat loop if you want to have all the changes occur after last
resize, kind of animation
repeat for each line aMessage in the pendingMessages
if aMessage contains "adjustRatio" then cancel item 1 of aMessage
end repeat
send "adJustRatio pNewWidth, pNewHeight, pOldWidth, pOldHeight" to me in
0 milliseconds
end resizeStack
on adJustRatio pNewWidth, pNewHeight, pOldWidth, pOldHeight
put round (pNewWidth / 2) into tNewHeight
put the rect of me into tRect
put item 2 of tRect + tNewHeight into item 4 of tRect
set the rect of me to tRect
end adJustRatio
-----------------------------------------------------------
