Bit of a bizarre problem this - certainly not serious, but it can be a bit of a pain. When I reboot my system, I can't use the scoll button on my mouse. If I go into my mouse settings, change the scroll settings, then set them back again and save my changes, it works OK. Exactly the same settings. The bizarre thing is that it's only started happening over the past week or two. Anyone have any idea what's going on, or what I can do to solve the issue? I'm running the latest drivers, and beyond that, I haven't a clue what to do.
