WMLute did you get the message "combat trim off" when pressing ctrl x? If not i believe you have remapped the key. I just ran the same test with ctrl x and all worked as expected.

Yes I verified that I got the orange message.
I will pop online now real quick and triple check this.
(edit: Ok, here is what I just learned.
If you are using X Auto Level and turn off Combat Trim Ctrl X, you get the message that Combat Trim is OFF BUT when you disengage auto level it turns back on again.
You have to break off auto level to turn off Combat Trim.
So oak, if you can, next time you are up make sure you are NOT using Auto Level (X) when you turn off Combat Trim and see if that was what happened.
