Lately, my mouse keys have been doing something strange. When I push one button, it will sometimes jump two spaces instead of one. Anyone heard of this or know how to stop it? I don't care if it jumps two or one space, I just want it to be consistent.

The fact that it's inconsistent leads me to believe it isn't a setting.

 

Probable problem/solutions:

-Messed up bytes, use Malwarebytes Anti-Malware

-Not updated driver, update your driver (Highly unlikely in my opinion)

-Clean your keyboard? Could be something stuck under it or something is making the button stick twice or once. (Sounds ridiculous, but you should start here)

-Your RAM is being eaten up, making your computer lag frequently so it multiprocesses.

 

Does it only occur for spacing? By MouseKeys you mean Keyboard Keys right? Did this happen after an update? After you downloaded something? Does it only occur in Runescape or happen all the time? Does it happen in notepad or wordpad? Etc.

Can't be my keyboard, tried to see if it did it with an on screen keyboard and it does not. Only use mouse keys for rs, but i just tried getting it to happen in notepad and it did not. By spacing do you mean 4, 8, 6, 2, 7, 9, 1, 3? then yes it only does it for those and apparently only in rs.

Is there a split second delay before the 2nd jump, or does it just instantly jump twice the normal space. I had a problem where the typical keypress would cause it to do a very fast "jump-jump" and a very delicate, quick keypress would cause it to jump only once. I searched everywhere for the answer and found nothing, I ended up doing a format because I needed to anyway, and that was the only thing I could find to fix it. If you have the exact same problem, good luck figure it out, please post if you do find the answer.

Umm try disabling "Enhance pointer precision" under your MOUSE settings.
