I'm using WI on Mac OS X.
When i'm in 3 states panel there is a bug with toolbars, actions from all views are append resulting to an ugly rendering.
I have not yet found a way to 100% reproduce it but i often got this bug and i have to close/reopen WI to fix the problem.
That's strange. I've never seen anything like this so perhaps it's a mac-only issue. Let me know if you find something.
Regards,
Michał
