Page nav bar dropdowns are appearing behind one of the sidebars in IE 7 & 8. They work correctly in IE 6, Safari and FireFox. The offending sidebar contains a swf (culumus plugin). Its just the interaction between the swf and the pulldown that is the issue. Have tested this by reordering the contents of that sidebar and the pull downs work as expected but the second I put the swf at the top of the sidebar the pulldowns hide behind it. They of course pop out when you resize the window. Ordinarily in these situations I would adjust the z-index so the nav bar is on top but a look thru your code and I see that you've already set this for 999 and you have some IE hacks for the nav bar. See the site at paradoxprocess.org
Also important to note that I used the code from another post to center the nav bar:
ul#rmenu2 {border: 0;}
div.rMenu-center {border: solid 1px #ae6521;background-color: #ae6521;}
Do you have any suggestions on what might allow the nav bar to dropdown over the swf in IE 7 & 8? Please let me know. Thanks!
