--- Comment #4 from Joe Russell russell.josephrussell@gmail.com --- Update:
So after thinking it could have been my mouse (it was 4 years old roughly) I went out and bought a new mouse (needed it anyway) (corsair scimitar) and started playing. The game worked smoothly. No issues UNTIL I started to use diablo's audio chat. After using the in game audio chat with a buddy of mine who was in the same game with me I ran into the moving and channeling issue where it seems as though the mouse button was being released. When I exited the game and closed battle.net down completely and restarted it, quit the audio chat and started a new game without it the game worked fine. Not sure what the issue could be or if someone else can replicate it, maybe it's just me. Thanks in advance!
