I use ZZTakeoff on a Mac, when I am viewing plans I cannot use right click to drag around on plans. This works without issue on PC, I was previously using an apple magic mouse on mac and it didn't work. I just purchased a standard mouse with real left/right click, and I still cannot use right click to drag plans.
Thanks for the bug report. We will dig into this.
We have found and resolved the issue locally. The fix will go out with our next release. Looks like Mac treats right click slightly differently, so we just had to make a small work-around.
