Distribute Spacing Stuck on Pixels
The distribute spacing is set to pixels, but doesn't show any measurement. This took some trial and error to find out it was pixels. Trying to override it by typing in say "2in" only gives you an error sound and doesn't change anything.
It seems to only show the document units after playing with a few object with the panel open. I've had limited success with changing the document units to something else and then back again.
