I have no idea why this started, but suddenly I can't attack or interact with anything while mounted. For example, I can't charge or heroic leap from mount, paladin can't throw his shield, etc. When I hover over a target, I do not get a sword cursor, it stays as a fingerpoint cursor only. I do not have any new mods and can't really think of any updates to those I do use. I've looked in options and keybindings but can't find anything related. I have searched online here at MMO-Champion, Blizzard forums, and other resources.
Anyone else seen this happen lately, for no apparent reason? Any suggestions are appreciated. ty
