Stack Size Changes

My query from earlier this morning is generating a non-flurry of replies, likely because no one knows the answer.

I have solved the problem with a simple preOpenStack handler, which works fine. However, I feel this issue must represent a gap in my knowledge, which I would like to close.

Further investigation:

On suspendStack
answer the height of this stack
pass suspendStack
end suspendStack

The height is 742

Same for on closeStack -- last instruction before stack closes -- the height is 742

On preOpenStack
answer the height of this stack -- first instruction, before doing anything else
pass preOpenStack
end preOpenStack

The height is 712 on some occasions. On other occasions it might be 692 or 696, and so on.

The width does not change.

Is this a possible bug? Is this a feature I don't know about?

It's on a laptop, but the rect of the stack is smaller than the screenRect.
