Words Cut Off When Recording

I LOVE Audacity, and have been happy till now. Since the last Windows7 Update on 10-09-12, I got blank spots when playing back a recording, OR a short buzzing noise. The buzzing has gone since the upgrade to 2.0.2, but I still get words cut off, like it didn’t record anything at the end of a word. I had Audacity 1.3 Beta, just upgraded to 2.0.2, using audacity-win-2.0.2.exe. on 10-09-12.

Last Windows7 Update on 10-09-12

Here’s my Setup:
