I sympathise with you, Larry Larry, My arthritic fingers totally understand your touchpad difficulties. There are a couple of different problems that I have observed with uncoordinated fingers and touchpads. One is accidental touching of the touchpad and performing a mouse click. The other is accidentally dragging your thumb across the mousepad while typing and moving the cursor to some random location in your document. The first either is easy to fix or unfixable depending on what touchpad driver your computer has, or has available. Check to see if your computer has Synaptics driver either installed or available to be downloaded. You can disable the touch-click feature with Synaptics software.
The other problem is a bit more complicated to fix and requires some third party software. There are a couple of software fixes that totally disable the touchpad while typing. This disabling and re-enabling is smooth and you do not notice it is happening. It has been several months since I installed this "thumb drag" software and I forget the name of it. (out of sight-out of mind?) It is listed by How-to-Geek
www.howtogeek.com at the bottom of every web page. A Download.com, Softpedia.com, Tucows.com, etc. search will reveal some additional software.
As a last resort if everything else fails; I used to tape a piece of cardboard over the touchpad (piece of cereal box cut to size), leaving the buttons exposed, and use an external mouse. I had to use this method for my first couple of laptops. Place one strip of tape across the top of the cardboard so you can easily lift it to use the mousepad temporarily if needed.
I realize I have kinda jumbled the information I am trying to pass on to you here. If you need more information, post back and maybe my mind will be a bit sharper next time and I can remember procedures a bit better.
