I was having problems running Buzz on my Toshiba laptop with WinXp, it would always say "BUZZ unexpectedly has to quit." whenever I started buzz - I was Able to fix this problem by:
1.) right click on the BUZZ icon and select > Properties.
2.) When the properties window pops up selct the Compatibility tab atthe top.
3.) Under the Compatibility mode check the "Run this program in compatibilty mode for: box. Then select Windows 2000.
