Toshiba Satellite TouchPad issues

Googled and found your site to find you solved a LOT of problems with Toshiba Satellite Touchpads. Have tried 2-3 cures and still have a problem.

My TouchPad is functioning but VERY erratic. I spent 3 hours creating a Visio org chart today and was ready to pull my hair out when using dynamic connectors.

I've checked for malware and viruses. CLEAN. I've tried battery removal-power disconnect, holding power button 15-20 seconds, F2, then reset and F10 to save. No good. Tried downloading driver and Windows (7 home edition) can't find it. I adjusted mouse settings fully to right and still..., jumps all over the place when I use it.

What am I missing? I've read through scores of support requests with solutions and thank you's galore. I'd like to send one too!

Thanks
