I work for a company whose IT department has a group policy enforced so that our screens lock after 10 minutes of inactivity.  That’s great in theory, but I run my corporate workstation inside VMware, which means I’m back and forth between different windows all the time.  When I go away from my Windows VM for 10 minutes and come back, the screen is locked – pain in the rear.

Jason Hall of Quest pointed out the fix: a free screensaver prevention app called Caffeine.  On Windows 2000 and Windows XP, it does a left-shift-up event every minute, thereby defeating screen saver lockouts.  Add a shortcut to it in your Startup menu, and presto, never get locked out again.
