I've gotten my Commander to disengage by holding the blade firmly in my left hand and twisting the handle counter-clockwise with my right--in a tight grip, the right hand index finger will pull back the liner lock.
However, I've also been able to disengage a Benchmade 970ST, Spyderco Military and a Mission MPF in the same way (got the idea from someone in another thread who said MPF's were easy to disengage this way). What seems to make this possible, apart from the MPF for different reasons, is that the liner lock has small "serrations" which I'm sure are put there to catch skin so that it is easier to release the lock in order to close the knife. Problem is in a twisting motion, it also catches skin and disengages the lock at a time when you don't want it to.
Yeah it bugs me a little, but as long as I don't have to do a lot of twisting with my knives I think it will be ok.
