When interacting with an npc after autorunning up to the npc and then toggling autorun off can cause a clicklock when right clicking on the npc to interact with it. focing me to right click the npc again stopstop my camera spinning.
The same thing is happening to me. I was just about to post something when I saw your comment.
I have no addons and I tried a reset and relog. This is happening with more than one character.
When I click on an NPC to either start a dialogue (usually clicking on a quest) or click on corpses to pick up loot, it takes 3 key presses now. The first key press, the cursor disappears and it’s as if my right mouse button is held down. I have to click again twice more to get the interaction working properly.
Same thing happening to me, did you find a solution?
