Command keys not working together in Illustrator
When I try to use two command keys together in Illustrator, one of them stops working. For instance:
-Shift+Drag (constrain proportions) PLUS Option+Drag (lock the movement along a certain axis).
-Shift+Drag (constrain proportions) PLUS Command+Drag (create a new shape using the starting point as its center).
I can do one or the other, but apparently I can't do both at the same time now.
I have tried this in Photoshop and it works fine. I have updated to the latest Illustrator CC version (updated today, 5th June 2017 but the problem persists. I'm working on a Macbook Pro with Sierra (10.12.3)
I have searched the forums and couldn't find a topic about this exact same problem, so I was wondering if someone might have a solution.
Thanks in advance.
