Zooming In/Out Buttons Are Grayed Out
FMP Pro Adv 13.0 v1
Operating system version
Description of the issue
I've been using FMP 13 Advanced for several months creating mostly 1000x700px layouts. I've always been able to zoom in or out until recently. Yesterday, I created a layout using for the iPhone.
The zoom level says, "100%" but I've noticed that I can no longer zoom in or out...the "+" and "-" are both grayed out.
Steps to reproduce the problem
If I open a different file or create a brand new one, things are okay. But every time I go back to that particular file, I can't zoom.
I obviously closed and reopened the file. I've tried closing the program and relaunching. Even tried restarting the computer. All without success.
