I would assume that Thomas sees that the leak is always the same size.

I've found this to be a common occurrence with VC in debug mode when using
dlls that allocate memory on startup, and don't free until after VC's memory
debugger has reported the leak. I recently saw a newsgroup posting that
purported to have a 'fix' for this issue. Unfortunately I can't
remember(oldtimers disease) the newsgroup, or the message text. I'm sure it
was within the last month somewhere under microsoft.public.* or comp.os.*.
I'll see if I can track it down.
