mega menu appears when the cursor is on hidden area

[kevblucasuni]

Hello,
sorry i only just noticed I could message on here I have already put this on Wordpress forum but I think I'll be better on here.
I really love this plugin but I’ve found a weird fault when I hover over the area where the mega menu area should appear it makes the mega menu appear but I only need it to do this when the user hovers over the navigation menu title that is associated with the mega menu.

thanks in advanced for the help
