Guild Wars 2

Hi, I’m first time here.
I’ve been searching forum for camera issue or rmb problem but I did’t find answer.
I got a video with the problem , it isn’t mine but it’s the same problem. When I let the RMB go while runing. Please see the video.

If anyone could help it would be great

Hi, i have solved this problem. I’ve uninstalled the windows.old folder with this way: https://www.sevenforums.com/tutorials/19151-windows-old-folder-delete.html and also uninstalled old useless wireless mouse driver, cause I use a wire mouse. Maybe it helps by other gamers.
