Stop linking "undo" list of action to all opened files....
When I do "undo" in a file, and then realized that Excel jumped in other list open files to continue to undo things, it really annoys me. I always have many Excel files open. And they cover different topics. When I want to undo actions, it is ALWAYS related to list of actions in one file, and never across many files.
I agree!!! It is so, So, SO annoying!
