johnnystell,
I had the same problem with XP Home not only with Microstudio but with other program also.
What I did was to install a software call xteq, this is the perfect software to cure some windows problems, it's a MUST with Windows Me!
The beauty is that it's Freeware, take the time to read what it can do and you'll find the option where it says how to shut down programs for you!
www.xteq.com
Also, Magix audio will not play cdg.
Good Luck
