Wow! Until I read this message it didn't occur to me that the
preOpenStack in the main stack of the database app I'm working on was
being called (I just checked) every time one of the five or six
substacks opens. Since that handler opens the database and reads much
of it into RAM, that would have gotten pretty awful if I hadn't known
until there was a lot of data in there . . .
This is a pretty bad pitfall. I've been surprised by this before
(though I forgot it) -- that "preOpenStack" doesn't mean, as it so
obviously seems to, "preOpenTHISStack" it means this stack and all
its substacks . . .

Thanks for responding Jacque,
As I said before in other questions to the group I've apparently
suffered
some sort of corruption. These three windows all open to the full
screen every
time. It doesn't matter that I resize and save them. They still
open full
screen
size the next time. Someone told me how to fix the preference
panel and that
worked. I was just hoping I could fix the other three panels in a
similar
fashion. If these windows are in a stack I could address the
problems with an
openCard or openStack handler.
I've run into something similar, and it had to do with the fact
that I had a
preOpenStack handler that was doing some automatic sizing of a
stack, but
forgot to set it up so that ONLY the main stack got the message...
here's an
example:
In the mainstack I had this stack script:
on openStack
set the rect of this stack to the screenRect
end openStack
And it had three substacks. Two of them hand their own 'openStack'
handler,
but the third one didn't. We couldn't figure out why the third one was
opening to fill the screen until we finally realized that the
'openStack'
message that went to the substack was not being trapped by it and was
falling through to the mainstack. The code *should* have been either:
on openStack
if the owner of the target is me then
set the rect of this stack to the screenRect
else
pass openStack
end if
end openStack
OR, I should have moved the original code into the CARD and not
leave it in
the STACK.
Is it possible that you have a plugin, library, backscript or
frontscirpt
that might be encountering this same kind of situation?
