...reverting back to WMP 10? Or simply uninstalling, then reinstalling WMP 11? Other members here seem to report similar issues with WMP 11 as well. Likewise, IE7 can cause issues with a variety of programs if the computer isn't free and clear of all junk files.
Have you tried updating all your audio and video drivers?
Although you reported it, I don't think being left handed is the source of the issue? (Just kidding.)

Cleanup Things To Do
Hope this helps.
WMP 11 often causes my PC to freeze simply by attempting to open it. When it does open, 75% of the time, it will stall and then freeze. My machine is a one year old Compaq Presario V4000 laptop, Pentium M 730, 80 GB 4200 HD, Intel Graphics Pentium 900. My OS is Windows XP/ Home. I use IE7 And I'm left handed. Any advice? ~ toc
