Control Panel -> Ease of Access Center -> Make the mouse easier to use -> On make the mouse easier to use window under See Also (below), Click on "Mouse settings" (blue link)to open the Mouse Properties -> Click on "Button"s tab, under double click speed", adjust the speed to your liking. Double click on the small folder to test. At Slow setting the folder opens and close at slow and high speed mouse clicks, while high speed setting only works for high speed mouse double clicks. In your case I would choose high speed settings where slow mouse double clicks are ignored, while on slow speed settings high speed mouse double click are not.
Hope I could help
