I know this won't be very useful but I want to rule out a few things if I can and some food for thought.Random mouse movements could be possibly be a technical fault with the mouse, or maybe a virus of some kind? If you replace the current mouse you're using, do this solve the problem? Is your firewall up to date? How about your drivers, are they all up to date? Has your mouse sensitivity options been set too high in control panel?Silkroad URL icon is worrying, but did you save the page at all by accidentally hitting Ctrl + S, I've done it once before and it freaked me out. I'd also make sure you do 3 passes when removing it just to be safe if you're not on a dedicated system.If the normal startpage isn't checking up, perhaps it is just a temporary problem with the circuit you're running, try hitting Ctrl + F5 using a new identity and see if that works, or does it simply not even attempt to load the page?Just some things for you to look in to.
