INCREDIBLE! 
Annie, we have never heard of this problem before. Are you running the newest Microstudio V2.103 demo?
For an application program, that has proven to work with many users, to terminate and restart your computer tells me your Windows installation or something else is really messed up. Do you have any other programs that are causing this problem or other random problems?
We have shipped AT/XT/PC/ATX Windows audio workstation computers since 1986 and we have never heard of this a single time.
Please understand, I'm not criticizing you. We are just amazed that our little ol' program has such power in your computer!
I would strongly suggest you have a PC/Windows expert check out your Windows installation, or reinstall Windows. Are you running Win98 Service Release Pack 2?
