Some time ago I started getting some weird mouse problems. When I hold the left button down and try to paint over some text, it 'releases' the pressing mid-painting while I still have the left button pressed. Now it also double clicks randomly when I only single click. I have two mouses and both seem to have similar problem. The mouses aren't new anymore so it's possible that it's a dust or wearing problem. I cleaned the other mouse already by opening it up and clearing the dust inside, couldn't see any wear and tear but with the new mouses the components are so small that it's difficult to visually see any damage. I also have Win 10 so I'm also thinking that it might be a problem. I guess there is no way of knowing if the problem lies with the mouses (mice) or with Win 10? I've tried fiddling with the mouse settings, hasn't really helped. I guess only solution might be new mouse?
