Has it worked for you since the patch? From a quick bit of reading comments on WoW Interface it looks like it didn't work for a while, then they fixed it and it did. But it's not working for me now, so I assumed the patch broke it again. Everything works but the unit menu.
UPDATE: From the developer of Clique:
I've uploaded a new version that bumps the table of contents and fixes an issue with the 'show menu' binding. You may need to remove the binding and re-add it, but it should work correctly now.
I'm pretty sure I've donated to him before, but I really need to do it again. I use my car less than his app. Edited, Mar 6th 2013 6:59am by teacake
