you know the list of things to do when you right click? for some reason, the list pops up everytime i left click. i want it back on right click, but i dont know how.

Go to your 'Mouse Properties' in your Control Panel. Where it says 'Button Configuration', unclick where it says 'Switch Primary and Secondary' buttons.

i've tried that. it didn't work.

The settings were probably altered. I'd look in the Mouse Properties, maybe try to go to Advanced configuration, and I'd try to see if the mouse came with any program, then I'd look in the program.
