Submenu items don't always run when clicked once (3.2.4)

I have a menu with some commonly used tools placed on it. I have added a menu to this menu with some of my chess products. Every time I attempt to click on one of the items in the chess submenu, the item will not run. I then have to go back and click sometimes up to three times to get the item to run. Usually it works the second time. All of the main menu items work with just one click. Let me know if you need me to send you anything to assist with this.

By the way, this is a terrific product. You have done a wonderful job with this and I appluad you =D>
