Incorrect double click on occasion when using a USB mouse

Not sure if this is the best forum, but here it goes...

I am on a T43 laptop and running XOrg/XFce.

When I use the touchpad and buttons on the laptop I don't have any issues at all. However, if I use my "Optical Mouse Blue USB" from Microsoft, I occasionally get a double-click when I single-click the mouse button. I am not sure how to troubleshoot this.

xorg.conf:

The only thing that may be wrong is I don't seem to have the "synaptics" driver installed, although the touch pad is working fine.

Lose either Track_Point or USB_mouse InputDevice section - they both reading the same device (/dev/input/mice) so you basically getting double of everything - movements, button presses, etc.

I also would recommend installing synaptics driver as it allows you to control sensitivity of the touchpad (but the should work OK even without the synaptics driver).
