If you're dropdown works in IE7, then you would just have to stick this into the head and it would work in IE8 too:
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />

What you might experience isa 'sticky' dropdown.
Google for 'IE7 sticky hover bug' and you would certainly find a lot of fixes for this.

Unfortunately that did not do the trick.

i have googled everything under the sun and can not find what might be causing the issue.

Can we see some corresponding HTML, or better still, a web page?

Apologies, I'm new here, so need to review those
