With an object selected on the MEP 2016 Premium timeline, I'm getting strangely inconsistent behaviour when I use Right click > Movement > Zoom Out (or In). On a minority of occasions I get an exaggerated zoom range of 156 to 64, instead of the correct 126 to 100. With a zoom in, I sometmes get 100 to 156 instead of 100 to 126.
Similar unexpected results sometimes using Movement > Pan.
It's always the first time I apply the effect. If I reset and try again, it's OK.
