Windows 7: Jumping cursor

Jumping cursor

I have a new HP laptop (dv6-1375dx) with pre-installed W 7 whose touchpad is listed as a "Synaptics Touchpad V14.0.3.0 on PS/2 Port".

The cursor has a mind of its own and frequently jumps all over the screen when I type without (I think) my touching anything. I've played with the sensitivity controls (palm sensitivity is now at maximum!) and updated the driver first from HP and then from Synaptics (is now 8/27/2009, version 14.0.3.0), with no help.

The device manager shows 2 mice pointing devices:
"Synaptics Touchpad V6.5 on PS/2 Port" (which is enabled)
HID-compliant mouse (which I disabled in my attempts to fix the cursor)

Now, I have noticed something that could provide a clue to the experts here.
After I updated the touchpad driver with the Synaptics driver I thought I had things fixed because the cursor did not jump as much, but with time it got bad again. I usually do not reboot my laptop but set closing the lid to suspend. When I reboot full, the cursor is better for some time and then deteriorates which suggests (and I know nothing about this) that its "memory" or whatever gets corrupted and needs refreshing with a reboot. Could be off base but thought to ask.

I've used several laptops before this one and am therefore familiar with touchpads. This is my first W 7 touchpad and it is driving me crazy.
