[comp.sys.mac.hypercard] Memory Management in HC 1.2.2

Hi,

I've got kind of a strange problem.

We've got a large system of stacks that serves as a
kiosk (or information center) for our library.  When
the system sits idle for a certain period of time
(currently about 5 minutes) it goes into "attractor
mode".  In "attractor mode", it simply cycles through
some predetermined set of cards, pausing on each card
for a few seconds, waiting for a new user to approach
and click the mouse.  (This severs to show potential
users the kinds of information contained in the system.)

The problem is that each time through this loop,
HC is loosing about 1K of heapSpace, and after about
1 1/2 hours HC locks up and we have to reboot.

Does anybody have any ideas?  I decided not to post
the script which does this "attractor mode" in this
first message, thinking that someone would have a
general answer.  However, if it would be helpful
to see the handler, let me know and I'll post.
