terrya64 -
I posted a thread on a similar (perhaps identical) problem a few months back:
http://yabb.jriver.com/interact/index.php?topic=38989.0I tried everything I could think of to solve the problem (uninstall/reinstall, clean install of the OS (W2K), different OS (XP), etc.) with no success.
Then I started tinkering with the "General Options" for MC12. I finally got the memory-eating behavior to stop by UN-checking EVERY item under "Tools > Options > General > Advanced > Features" except "My Computer", "Split View", "Start" and "Theater View". MC12 has been running on my server for weeks configured this way and it has been bulletproof as far as memory usage is concerned.
This configuration works for me because I don't use video playback, podcasts, portable devices, etc. (I just use MC as a whole-house audio server). If you have more complex requirements then this approach may not solve your problem.
You may be able to identify which option/feature is related to the memory problem by enabling/disabling them one at a time - I didn't bother because it's doing what I need it to do for now.
Good luck...
