It hasn't worked for me for a while. I've tried using the 'keybindings' option and resetting the keys to no avail. Is this expected to work?

was just playing around with it change line 89 of Addons\ovale\dist\ActionBar.lua to read as

name = "CLICK BT4Button" .. slot .. ":LeftButton"

its just an issue of a space where there shouldn't be one

This fixed it for me. THANKS!

(There was a space between BT4Button and the end quote. I simply removed it as directed)
