I am able to use the default action binding (bound to F/MiddleMouse by default), but I cannot use the selected action binding (bound to PrimaryMouse by default). So unless what I want to do is the first suggested action when hovering over the item, I am in a pickle.

I was able to fix the issue by deleting my 'DayZ' and 'DayZ Other Profiles' folders in 'Documents'. Anyone else with this issue should try it as well.

I would like to bump this as well. I can use the F/Middle mouse to use default actions, but I cannot use any key to use the selected action in the scroll menu.
