Problem with touchpad driver

Hello

I have HP Pavilion zv5403EA notebook and I have a problem with ALPS
touchpad drivers. The problem is that when I have drivers installed, I
have sometimes problems with my keyboard. The symptoms are that the
keys tend to block (for example when I play a game, after releasing for
example forward button, my character still walks forward - I have to
press it again to stop it). It does not depend on software, game, and
happens randomly - I can re-arrange keys, but the problem still
persists. When I uninstall touchpad drivers, the problem disappears...
But I would like to have some functions of my touchpad, for example
scrolling, because when it uses ordinary Windows mouse driver, its
features are disabled.

Does anyone have the same problem? How to solve it?...

I would be grateful for any help.

Krzysiek.
