Have you installed a color icon (cicn), in your System File or application
for the "hand" icon (the one displayed by StopAlert)?  There is
a bug in the Dialog Manager that causes it to use PlotCIcon incorrectly and
leave an 8K of unreferenced memory in the heap.

I reported this one to MacDTS over a year ago, but haven't gone back to see
if it's been fixed in 6.0.x (it's never appeared in any "Fixed Bugs" list
I've seen).  If someone at MacDTS wants to follow up, Paul Mercer responded
to my original mail message, acknowledging that he'd reproduced the bug...

Meantime the workarounds are obvious: use plain Alert(), or rip the
cicn out.
