CSS dropdow problem

[cwells10]

Newbie. Be kind. I am having a weird problem with a dropdown menu on a site I am working on. Works fine with Firefox, Opera, and Chrome. The problem occurs with IE9 and not all computers with IE9. On at least a dozen at my work have been having the problem. The problem is that the li items show up when you scroll on the parents but as soon as the mouse moves off the parent they disappear. On all of the computers in my section it looks fine but of course it screws up on some of the bosses computers

The same people are having problems with the dropdown showing up behind the scroll image on the home page. I changed the z-index which I hope fixes that problem.

I am at a lose and trying everything I can think of and find on the web.

The site is http://www.stpete.org/police/sppd-fluid4/index.html

Any help would be much appreciated.

I remember having a similar problem some years ago, in a different setting though. I solved it by giving the elements that disappeared on mouseout (and that were not supposed to disappear) a negative margin-top value. You could try to give the problematic li's margin-top: -2px, or something like that.
