What steps will reproduce the problem?
1. I've tried all of the button combinations but instead of working it opens up the tradeskill window to the cooking tab.  At first I had the Skillet addon installed but it did the same thing after I disabled Skillet.  I'm using Elv UI for my basic UI and no other tradeskill addons.
2. Specifically in this instance, I was trying to cut a gem.  It was a gem I knew how to cut but instead of giving the option with the cuts, it opens to the tradeskill window (cooking) on first click and closes it on the second click (on the gem)
3.

What is the expected output? What do you see instead?

What version of the product are you using?  Latest version
