I get the following error when I run a VBA macro on a machine other than the
one used to write the code:

"Solver: An unexpected internal error occurred, or available memory was
exhausted."

The interesting thing is that when I open and run Solver from the menu, it
initializes and works properly thereafter.

I found an article describing a problem with Office 2000 that is quite
similar (if not the same thing) but nothing for Office XP 2003.

I suspect the problem has something to do with the initialization of Solver
or perhaps a path.
