Memory leak, once again.

I have been browsing the posts in this group, but was not able to find
anything to solve my problem.
I have a feeling Mathematica still has a memory leak, and a severe one,
but cannot locate it. I wonder if anybody can help me.
------------------------------------------------
I have a code for some algebraic computations - no images,no sounds, no
files.
I load the initial data, MemoryInUse shows about 3MB used.
I run the evaluation. Say in the current example in succeeds to
evaluate the needed data at 22MB.
Then I run the
Remove["Global`"] command (the only non-system context I have),
then I also use the CleanSlate utility to clear In and Out things.
I look at the MemoryInUse again and it shows about 19MB used.
------------------------------------------------
So it seems I have cleared all my input data, but the memory is still
used. Share[] does nothing as well. So could there probably be some
hidden system variable that stored something weird?
------------------------------------------------
I understand that 19MB is nothing, but the problem is that the memory
used keeps going up constantly, and much faster that the growth of the
data set I have. So it makes me incapable of evaluating example I need.
-------------------------------------------------
If it can help, I am on Mathematica 5.0, Windows XP
-------------------------------------------------
Thanks to everybody in advance!
