Hey there,
I’m playing Cata Classic and have been experiencing the right/left click bug where I can’t use the mouse to turn. I can double click to run forward and can use the right and left clicks to click things but can’t use the mouse to look around. This makes the game unplayable as I have to use WASD to move exclusively. I had this bug kick in while raiding Firelands and was a massive hindrance. I installed an addon while in the middle of the raid and that’s when it started.
I have since tried everything I’ve seen online to fix the issue and have an open ticket to try to resolve the issue but they said to consult forums. I have reset UI many times, deleted all addons and supporting programs. I reinstalled the game multiple times and tried different characters. Anyone have any insight? All the posts I see about this issue are several years old and with no apparent resolution that works for me.
