Programs close by themselves when using mouse with Laptop

[videobruce]

When I hook up a optical mouse to a Laptop (Comtrash Presario 730) after a varible amount of time when using Opera V6 or Mozila V1.5 the browser closes all of a sudden.
This is closing NOT crashing. What seems to be happening is the mouse cursor jumps to the upper right corner and performs a left click function before I even know it. I know this because after the browser closes, the cursor is at that corner.
I have tried another optical mouse and the same thing.
The touchpad software is installed and when the system detects the other mouse I get a dialog box stating that some feature(s) are disabled because of the mouse connected.
The FAQ's said that a mouse can be used along with the touchpad (which can still be used).
I believe it happened with another program other than a browser. I really don't think it is that browser.
I usually happens when I'm either waiting for a page to load or just moving the curser around.
I know that I didn't press the left click button when it happens and not anywhere near that upper left corner.
I''m running 2k w/sp3 if that matters.
I have disabled the touchpad.

Any ideas??

usually i've notied that on newer lappys they have this thing where if you tap the mouse pad it's the same as clicking a button, which could be accidentally engaged which just happens to close a window.

maybe the touchpad wasn't totally disabled (I wouldn't put it past compaq).

Have you gone into the system properties and ensured that all traces of the touchpad have been disabled?

I checked the touchpad AND the left and right click buttons and they ARE disabled!!

Most of the time I'm NOT even touching the Laptop when it happens! I also have a very lomited amoiunt of processes running at startup, just what's needed.
