Thanks jeff, that seems to have fixed the problem.
In addition, I've noticed that for some programs, such as WinSCP and ConTeXT, when I use the "Minimize" gesture (down and to the left), the applications will not minimize to the task bar. Rather, they will minimize to a small window right above the Start button that has the mini icon, the name of the program, and the restore, maximize, and close buttons.
For your reference, WinSCP is pinned to my task bar, but ConTeXT is not. This doesn't happen for other applications like Firefox, Trillian, Windows Media Player, Notepad, PuTTY, etc.
This is inconvenient because I need to click the Restore or Maximize button in order to restore the program. Previously, I would be able to click on the button in the task bar to re-maximize the application. Also for your reference, I'm using the Windows Classic theme with Windows 7. I'm not a fan of Aero.
Thank you.
