Strange mouse behaviour after switching to evdev.

[Łukasz Maśko]

I have a Kensington SlimBlade BlueTooth mouse and I use it with my laptop. 
So far, I've used it with a mouse driver and had no problems - only 
left-right scrolling didn't work. Recently I've switched to evdev just to 
give it a try. Well... it works. Evdev recognizes all the buttons, even 
left-right scrolling works. But I'm noticing one strange behaviour - from 
time to time, ocasionally, the mouse pointer suddenly moves to the point 
(0,0), to the very left-top corner. Just like that, without any reason - I 
don't even touch my mouse. There are no reports in log files about these 
events. I had no such behaviour with mouse driver.

Have anyone noticed something similar? If yes, how can I fix it? It distroys 
nothing, just is a little annoying and sometimes disturbs working.
