on joomla site, Pages show, then disapear, only in ie6

strange bug, only in IE6. http://www.pagovernorsconferenceforwomen.org/

when you click on any of the navigation items, you get a page to load, for a second, then it disapears, and leaves only a blank browser window.

Has any开发者_JS百科one else dealt with an issue like this?

Could be the Peek-a-boo bug.

I notice that div#columns has a left float and is immediately followed by a clearing div.

Try "giving it layout", as described here.
