annoying mouse bug "catches" my cursor
Happens to me a fair bit, most often when trying to get a popup window out of my way with ESC while in the midst of a fight. My minimap gets caught and I’m wildly moving my mouse wondering why I’m running in one direction and the camera won’t respond.
Not sure how they’d go about fixing that. It could be an issue with the client not being able to respond quickly enough to input (or we’re just too fast for our ‘puters!) in certain cases where, as you suggested, things take focus and are highlighted briefly as the mouse passes over them or a quick mouse click is required to dismiss and we’re already moving the pointer to resume combat.
This is the brother to the “I’m stuck in my chat box!” monster.
