When launching a modal radwindow in IE 6, any dropdown's visible on the parent page are hidden. Once they are hidden, they are gone even after the modal has been closed. These are pure ASP.NET dropdownlists. There is nothing special about the dropdown's that are hidden - I can add new dropdowns to the page with nothing in them, and they still go away on launch. Any ideas out there?
I am using ASP.NET 3.5, 2009 Q3 of Telerik's ASP.NET AJAX Controls, testing with IE 6 (6.0.2600) on a virtual machine running Windows 2000.
While the issue was initially encountered on a much more complex page, I have created a brand new page, no css, just bare-bones elements, and it still happens in IE 6.

function ShowModal() {
var wnd = radopen('<%=ResolveUrl("~/register.aspx") %>', null);
wnd.set_modal(true);
wnd.center();
wnd.set_behaviors(Telerik.Web.UI.WindowBehaviors.Close + Telerik.Web.UI.WindowBehaviors.Move + Telerik.Web.UI.WindowBehaviors.Resize);
wnd.show();
return false;
}
</script>
</telerik:RadScriptBlock>
</form>
</body>
</html>
It appears that when showing the radwindow with modal being set to true, the dropdown's visibility attribute is being set to hidden. With modal being set to false, the dropdown is fine... Thanks
