I have to admit I'm with you here, Trevor. The current behavior has
never bothered me, and like Jerry, I use it to implement some things in
my apps. It seems trivial to add a single line that closes the stack,
which is what I do.
In my situation, the stacks I am accessing are very large. There would
be a delay if they had to be constantly opened and closed. I could live
with it if I had to set the destroystack to false, but it is convenient
to have them go away completely when I do open them visibly for editing.
