Here are a couple of replies from other users of Toshiba laptops who had
this same problem.

Finally, I found a fix for this annoying "feature." There is an option
with the touch pad called tap zones that Vista (or Toshiba) delivers as
enabled. Tap zones activate certain areas of the touchpad as shortcuts
for other functions (as if its too hard to click on the window minimize
box) Anyway, here is how to disable it:
Control Panel-->Mouse-->Device Settings-->Settings....
Expand the "tapping" module then single click the tap zones module.
Uncheck the Enable Tap Zones checkbox.

A new programmable Dual Mode touchpad features one-touch icons for launching
e-mail and Web browser applications and other user-selectable programs. You
can create custom tap zones in each corner to open the start menu, maximize
and minimize the current application, or run a program of your choosing.
Horizontal and vertical scrolling is also supported. We liked having the
ability to control most of the desktop from the touchpad, but it took some
getting used to. You'll have to keep an eye on where you're tapping, or you
may end up opening programs accidentally, as we did the first few times we
used it.
