Task Manager Gone...Help

[doc40]

I have searched through the numerous posts here and on XDA but have not seen anyone else with this issue or this issue addressed at all. At this point, I'm hoping someone who has the knowledge might point me to a fix.

My icon for task manager does not appear on my phone at all anymore. Not sure when it left or what made it disappear. I can do to settings and clear running programs but I liked the ability to touch one button and easily select what programs I wanted to kill.

Yes, I did go to start --> settings-->system-->task manger->button tab to ensure that I have the check box next to Enable Quick Menu on Today Screen checked. For some reason its not appearing.

I have checked it, unchecked it and rechecked it all followed with a soft reset in between and have received no changes.

Any other helpful thoughts would be greatly appreciated!
