When cursor over top nav everything below disappears

I used a custom template to create a site with SiteAssist Pro. Everything seems to work fine except in IE 8. Whenever the mouse is over the top navigation everything underneath the navigation bar disappears and I must refresh the page in order to view the content that is there (this is not a CSS MenuWriter menu but the same thing happened with the CSS MenuWriter menu). The website where this is happening is at www.estorestogo.com . I have an identical website without the SiteAssist Pro content at www.shoparoundalley.com and everything works fine which leads me to believe that it has something to do with SiteAssist Pro somehow not functioning properly with my template. Any help you can give me with this issue would be greatly appreciated as I am at a loss.

Thank you,

My guess would be the way that the z-index are set up is causing this. Try changing the z-index values around and see if the issue still occurs.

I'm not sure exactly how to do that. I'm not which z-index should be higher and which lower. Any help you can give me with this issue would be greatly appreciated.

Thank you,

I'm not quite sure what z-indexes you would have to change around. There's quite a few of them set so it'd take some experimenting to determine which ones might be causing the issue. Most likely any of the z-index that has to do with the content area you should try setting it higher.
