Every hour or so my melee button (numpad 5) will completely stop working, which causes me to be unable to re-bind it or *any* other move at all. I tried switching it to a keyboard key but when it happens, it doesn't allow me to switch anything at all. I'm using a Razer Naga mouse and Razer Chroma keyboard for reference. The only way to fix it appears to be running the scan/repair option on the Battle.net app, which is quite inconvenient since I'm having to do it multiple times a day. Deleting the cvar in appdata as suggested by a help article also does not resolve the issue. I was thinking this might've been related to the known issue with binding keys to the numpad, but I can actually bind it, it just randomly stops working. Any suggestion on how to fix it permanently or at least for more than an hour would be appreciated.
