WP 3.4.2, Mega Menu v1.3.10
Anim Effect: Fade In
Anim Speed: No Animation
This happens on the demo page too (http://www.designchemical.com/lab/demo-wordpress-jquery-mega-menu-plugin/), if you move your mouse back and forth across menu links quickly enough the middle one will stay permanently on/open.
Example: Demo page, the top grey 'Fast' demo, quickly hover over Products > Sale > About Us > Sale > Products.
The Sale menu dropdown never disappears.
Compare this for example, to the left categories menu on ebay.com, the response is absolutely instant and only one selection appears no matter how quickly you move the mouse up and down.
How can I get Mega Menu to be that responsive?
