A similar topic is posted elsewhere. This is different enough that I’m posting this.
After a macro has been dragged from the GS window (showing the question mark) and dropped onto an ActionKey, activating the key (macro) doesn’t work.
Ex. I drag a GS macro button (question mark) to the actionkey. My activate (mousewheel click) does nothing. The bar cycles a bit but otherwise nothing.
Ex 2: I drag a macro from the Blizzard macro box (“/m”) and it works perfectly on mousewheel spin.
In other words, I can drag direct Blizzard UI buttons to a button and they work. Buttons dragged from GSE window do nothing but appear to cycle.
