There is a somewhat serious bug in version 2.0 of Lightspeed Pascal
that everyone should know about. Everytime you execute your program
within Lightspeed, the system heap will expand by three handles 
totalling about 1K; this space cannot be recovered until you reboot
the system.

The problem will manifest itself, usually, by the system just
locking up on you - most likely occurring when you try running
your program about the 20th time or so.

I called Symantec about it, and they acknowledged the bug. Their
workaround is exactly as I said - reboot the machine. They are
working on the problem.

A suggestion, then, for Lightspeed users: keep the LightBug window
open with the system heap displayed. When the free+purgeable space
gets down to about 1-2K, do a reboot.

By the way, despite the problem, I am very pleased with the product
and think Symantec has done a great job with it.
