Works in IE6 but not IE7?

[BigAl75]

Instead of creating two seperate pages for every page on the website, I decided to use the csshover.htc file found online for my horizontal drop-down navigation. It works perfect in both FF and IE6, but when you hover over in Opera or IE7, the drop-down menu dissappears. It almost acts like it's on a timer, or there's a certain spot that triggers the menu to dissappear, because it goes away at almost the exact same place each time. I have been able to get it to stay if you hover very slowly over the sections in the drop-down, but I want it to work like it's supposed to (like in IE6 and FF).Has anyone ever experienced anything like this before? Anyone have any experience using the csshover.htc file? Right now, this is the only thing keeping the site from being ready to be uploaded to the server.I'm not going to post any code as of yet because I'm not sure what all you'll need to see, and I don't want to put up 6 different codeblocks when you only need 2.Al

OK, here goes (don't laugh, up until last month, I'd never designed a site layout using anything but table):html:

FIxed in IE7 using z-index, but the menu still disappears in Opera for no apparent reason.
