I've seen things like this before, too, Laura. Probably your mac heap
starts out small, and you ask for a bunch of memory during your startup and
(for some reason) it can't grow the mac heap to accomodate you. I usualy
set the mac heap to be pretty big as one of my first actions. Start up your
stuff and see how big it is. Then do a (set-mac-heap-size x) to make it
nearly that big when you start. That function is defined in qt-objects,
btw.
