New to this- IE 6 drop down menu problem...

OK, I am creating a microsite and it's almost comlpete, well when I opened the site in Internet explorer 6 I noticed once you roll over the drop menu it stays up. I have tried everything! It might be that I'm over thinking it but I'm about to pull my hair out. I have started a seperate style sheet for IE6, it works fine in all other browsers including IE7. The url is:

http://208.112.123.63/~bghcom/paypro/v2/index.php

And the services tab is the only one with a drop down. Any help on this is greatly appreciated...

Sorry for the delay in posting...
Did you get this solved?
If not, can you post the IE6 css for the navigation.

That is certainly a weird issue.

Here's my styles, I entered some styles into a new ie6 style sheet but nothing worked so it's blank right now other than some other site fixes:
