If you mean changing TRIMEXTENDMODE didn't work, that's only one of the relevant System Variables. It's about cutting-edge selection [new = automatically starts with everything selected; old = you had to hit Enter to tell it you wanted that]. But if you're talking about after cutting-edge selection, the previewing of what's going to be cut away if you pick on it:

I suspect that's the real topic of the original question, because of the wording "it is trying to process and predict trim that I do not want." That's controlled by the COMMANDPREVIEW System Variable [see Message 2]. You may want one or the other or both of those System Variables set for the old way.
