This morning, I discovered while using ResScan that the arrow keys would expand and contract the time scale. Both up/down and left/right (and the mouse wheel) did the time scale change.
Now, I discover it will not do that no matter what! None of the arrow keys do anything, nor the wheel.
What did I change to eliminate that function and how do I get it back?
(Aside: it sure was stupid (when it was working) that the left-right keys did the same thing as up/down. IMNSHO, the left-right should SLIDE the time scale, not expand/contract.)
