Ahhhh. I see what you mean. It is kind of ultra sensitive and that may be the problem - I hope.
Unfortunately, turning the touch pad off is not an easy thing to do in Windows 7 like it was in Vista or XP.
However, thank God for the internet because it gave me some pointers on how to resolve the problem.
BTW, it seems that I wasn't the only one trying to turn off the touch pad in Windows 7.
What I had to do was download the Synaptic driver from their website. This gave me the touch pad icon (which is absent in Windows 7 it seems). From there I was able to disable the touch pad.
Now I'm able to post normally it seems. I'm not getting characters interjected where I don't want them to be - so far.
Hey!!!!! It does look like you had the answer after all. Thanks!!! You're my hero!!!
