IE7 z-index bug

["charriso" <webforumsuser@xxxxxxxxxxxxxx>]

My Spry drop down menu appears behind the text on my pages in IE7, because of 
the apparently well-known bug in IE7's implementation of positioned elements 
and stacking contexts (http://therealcrisp.xs4all.nl/meuk/IE-zindexbug.html).

 Is there a solution, or will I have to create a different menu system for IE, 
and do some browser-sniffing? Bit of a drag, that...

 Here's the problem in action (if you use IE7...) go 
http://pagesperso-orange.fr/cjh/qohenje/grammar/nom/case.htm and click on the 
"MENU" icon in the top left of the screen...

 Thanks for any advice.
