Re: Memory Leak?

You should NEVER be calling GC.Collect.  For that matter, you really
shouldn't ever code for DoEvents.  Rather, do whatever it is you need
to do in a loop in a separate thread from the UI.  If I had more idea
who was calling this method, and who was changing the global
variables, then I could give better advice.
