Ken I think the problem that you are refering to about the
Graphics toolbox is **not** a bug! The Graphics toolbox uses TYPED
CONSTANTS and if you are running the GT in memory mode, it will only run
the first time correctly because typed constants are only initialized
once. (turbo manual : typed constants) Borland suggests compiling
to a .com file ****WITHOUT***** running the file. And your problems
should go away.
