Touchpad Issues

I have a small issue with my touchpad, I had the problem with it randomly moving the cursor (i.e. I would start typing and then it would move and be typing in a different spot) that was with the default windows mouse driver. Now i installed the proper touchpad drivers (7.0.1101.18 2/20/08) and disabled tapping, this solved the cursor problem but now (and almost at about the same rate as the other problem) I have another issue, basically I will be moving the cursor around and it will stick then a second or so later it will shoot off in the direction I was trying to move it. I know it isn't the computer freezing up for a second and it only happens with the Alps driver not the standard one. It is the only driver available on my manufacturers website and a quick google didn't turn up an alternative one. The computer is a emachines eme520.

 

Try some of the newer drivers HERE.

 

Thanks for your reply, should have mentioned I am running XP, was only vista drivers listed there. I tried them put the setup.exe wouldn't run (said incorrect windows version) and tried to manually update in device manager and said the *.inf file didn't contain any info about my devices.
I found a slightly new version, but it still seems to be doing it (maybe not quite as bad, but I could be imagining that). I believe it is a hardware issue, I think something else is causing a tap on it make it freeze for a second, whereas with the standard driver I can't disable tapping so rather than freezing it just clicks the cursor somewhere else.
