Dell Latitude E5400 Palm/Touchpad

Hi, I've had a Dell E5400 running Windows 7 32-bit and the Dell ALPS touchpad driver from January 2010 for the past few months and I continue to have a problem with my palm touching something (I think the touchpad) while I type...and you know the annoyance it causes while typing!

I was hoping someone could help me find a solution that doesn't involve disabling the touchpad. Does anyone have some optimal settings for the ALPS driver that won't make this happen as much as it does?

I think the 3 settings that may relate to this are:

Touch Sensitivity (I have it 1 notch below the middle towards light touch)
Tapping Speed (right in the middle)
TouchCheck (Enabled, and set far left to minimum)

Any assistance would be much appreciated.

 

bring touch sensitivity 1 notch below max
bring touchcheck 1 noth below max

 

Thanks, will try that out now!
