Ah, yes. Google Chrome! I too have had issues programming for it.
Unfortunately, I do not have a simple solution for Chrome specifically; however, I have found that a good solution using CSS Control Adapters. Not only for the Menu Control, but I also use them for GridView manipulation. It provides easily read markup and great CSS support!
Here's a link to help out. I have had success with this approach in IE, FF, and yes Chrome! Let me know how it goes if you choose to implement!
