Mega Menu fails to close

Enjoying this theme and its many good qualities.

I do seem to have a small problem. The mega menu fails to close sometimes. This only happens on the page with pricing tables and I wonder if there isn’t some sort of conflict going on between the two. The pricing tables page continues to function but the mega menu stays open to one of the menus which usually would ascend after the mouse leaves the area. Anyone have any experience with this?

Thanks

Tom
