ui.dialog drop down menu issue


I'm really racking them up today...
Is there an inbuilt way to get around the IE6 bug, where a drop-down
menu <select> 'shows through' DHTML layers...
In the past I've used an empty <iframe> resized to same size as the
dynamic layer (and floated one z-index below it) to 'kill' the select
boxes... but I just wondered if there was something in ui.dialog that
would do the same thing?
(I think there's a similar issue, where Flash movies show through
too...)
