While I was adding a source (RM7) the window suddenly resized (I'm sure I hit something but don't know what). Now the source view window extends all the way across the screen of my laptop, 13 1/2 inches. I cannot "undo" it, nor can I find a resize line to pull it back to normal. Hope this makes sense.
I then tried to back out of it and open it again with the same result. I also tried opening other source windows and they are all HUGE!
