I have the same issue. At the login screen, I select my user, enter the password, the mouse works fine at this point. Click on login, wait, screen comes up.... then at random, the mouse either works fine (about 1 time in 5) or it goes really really slow (4 times out of 5).
Only way I'm working around it is to reboot (usually 5 times ish) till it decides to work. As a test manager by trade I would say this is a P3 at least not a P4, as it's definitely a functional issue not cosmetic, albeit with an untidy workaround (many reboots).
