I tried using the DoEvents and it doesn't seem
to be working. I don't use any external functions, and I don't think
that I have anything recursive. I may be wrong about that last one.
Just as further background, the Mem Usage continually grows and the
only way to clean it out is the actually close the Excel application
itself. Not just the file. If Excel is still open, it still takes up
the same amount of memory.

Do you think you might be able to check out some items if I send you
the main sections of code? If not no worries. Any other ideas would
be helpful.
