Logitech G9x (Wired)
Funny thing is this only started happening to me yesterday. Before that, I can’t recall a single instance of it happening, either in open world PvE (crowded group events included) or in WvW. Now it happens all the time, and the amount of things happening on screen doesn’t seem to make a difference. My RMB will randomly stop functioning even in non-crowded areas w/out any events going on around me.
This pretty much makes the game unplayable for me because not only do I use my mouse for turning, but I also use it almost exclusively for forward movement via LMB+RMB (I alternate with Toggle auto-run depending on the situation).
I will also be submitting a ticket.
