Windows 7 laptop touchpad needs to be disabled

[Clockspiral]

Okay, I'll keep this short. I know how to disable the touchpad clicker thing, so that it's only being used to move around. What I don't know is why it continues every so often to re-enable itself so that I must go through the whole process all over again.
Is there a way to disable this function completely?!

The laptop is a Toshiba Satellite.

You should be able to disable the touchpad in the bios but that will most likely disable the pad and the buttons but it should be permanent.

I looked at several threads for the same problem but there were no answers.
