Issue found in version 0.9.39c.

1. create a toolbar, add a single button
2. enter button macro edit mode
3. code a button with a flyout with open on right mouse click option i.e.
   /flyout profession:any:linear:right:left:12:click:show
4. exit button macro edit mode
5. right click flyout
6. flyout does not open

No errors are displayed, flyout just doesn't show.
Coded button shows the default icon and works if you left-click the button.

If you /reload will the flyout show

Hrm this works for me. Just to be clear, you need a capital "A" in "Any" in the macro above. I modified the code such that it will work with either capitals or non-capital spellings.

There's some LUA errors that our popping up every so often, but a /reload fixes it. I'm not wanting to spend a lot of time working on fixing this code because I plan on rewriting it completely here in the future at some point. I'm just trying to patch it enough to get by
