Displayfusion supposed to work but didn't work. It must be a very complex problem. Let me try one more time.
Perhaps your problem is putting Windows into Lock (or even worse Hibernate). Whenever I've done something like that, it normally doesn't work out so well. If locking your computer, without turning it off, is important to you, why not look at some of the other ideas to locking such as with your phone (when you move away, the PC locks, when you move back, it unlocks). There are other options as well, search around. Basically anything that doesn't rely on the Windows OS to manage your problem.
I have the same problem. When i turn computer on from putting to sleep my TOS windows and TradIdeas windows are all moved to different screens/areas and not locked. Wish i could find a fix rather than spending 5 minutes each time rearranging them back.
