I use UE on a macbook and travel between home/work where I have external displays connected. I rarely shutdown as I always have some sort of work in progress.

Sometimes when I resume, I find that UE has repositioned the window off the top of the screen, so I can no longer reach the window frame and drag it back on-screen. The only solution I have found is to quit and restart, which can be a real nuisance, especially since I tend to use UE as a scratch pad for transient data.

Is there a better solution for this? I have never had this problem with any other apps.
