I am seeing the same thing. Also Win7 guest with Windows showing idle
process at 99%, but my system is showing VB at 100%. The VM is only
running a single CPU, so FreeBSD is still running OK, but the Win7
system seems to freeze up periodically.

9.1-PRERELEASE on amd64 updated yesterday (though it has been this way
since VB was updated to 4.1.18. Guest additions for 4.1.18
installed.All ports current. I'm thinking of backing off to 4.1.16.
