Hi..So a couple weeks ago I logged onto WoW to find that all my addon settings/UI set up had been reset. A couple days later I started noticing that my mouse movement seemed 'off'. It's not just in-game though..it seems like a general issue. I'm not so sure it's the mouse though because I tried a completely different mouse and it still felt 'off'. I'm not sure that another person would find anything 'off' about it but it just doesn't feel as smooth as it did prior to that weird UI reset. The best way I can think of to describe it is...that it feels like it drags a little when I make small movements or that it feels 'resistant' when making small movements. Large movements feel fine..it's just when I'm dragging it over short-tight distances on the screen. I've already tried the following:

PC mouse settings and in-game mouse settings
Synapse 2.0 settings
Different USB ports
Cleaned the bottom + the optical lense
Cleaned mouse pad
Tried a different mouse pad + no mouse pad

I just can't figure it out....it's driving me up the wall - any advice?
