Hi all... I hope you have any idea how to fix it...
This mouse is working well, and suddenly it moves fast and randomly to any corner of the screen, and keeps there until I lift it and start moving it again.
This is an 3 button (scroll) optical ps2 mouse that comes with the hp pavilion a830n.
I think this is not the mouse because I had the same problem with a logitech usb optical mouse (problem appeared less frequently that this time).
There is another pc with exactly the same hardware and this problem does not appear. However I think this a problem with some setting at hardware level.
Actually I'm using 3D-White scheme, ponter shadow enabled, the pointer speed to the fastest, to hide the pointer while typing, 3 lines for the scroll, 80 reports per second as sample rate (changed with no success), assuming wheel is present, input buffer lenght as 100 (changed too), fast initialization unchecked (changed too).
I replaced the mouse driver with the original one because no newer driver is provided at hp's site.
Thanks a lot.
