Multiple event and frame editors

[Gamerdude]

I feel really dumb asking this, but I can't find out how to turn this setting on for the life of me. How do I make it so when I open a new editor (whether it be event, frame, etc) the editor I was in doesn't go away? Right now if I have a frame editor open and then open the event editor, the frame editor goes away. I have un-maximized the editors and indeed only one editor is present at a time. I remember MMF1.5 being able to do this (and I also remember it crashing when I opened too many up, closed the program, and went to reopen it :P), but on this fresh install of MMF2 B254 I can't figure it out. Any help?
