I just upgraded recently to version 4. The submenus of my menu are not showing up in Chrome. They appear fine in IE and FF. Also, I've notice some lag in response when clicking on my menu headings. I will click them and at times there is no response and will have double click it. Never noticed this before on other menus and I have used this one before.
To see it in action go here: http://www.breathoflifecha.com/Retreats ... Again.html
If you click on 'our staff', 'retreats' or 'contact us', it will not respond sometimes. Please check the submenus as well in chrome.
I am using the first template under 'invisible top'.
