RoundedCornersExtender control problem

I've hit an issue with the screen "flickering" when i use the RoundedCornersExtender on multiple panels. It only happens if you place a drop down on one of the panels. If you get rid of the dropdowns it won't do it.

The funny thing is it only happens in IE...works fine in FireFox.

Anyone have any ideas?

here is the html for the page:

<%@dotnet.itags.org.PageLanguage="C#"AutoEventWireup="true"CodeFile="test.aspx.cs"Inherits="MasterPages_test" %>

<%@dotnet.itags.org.RegisterAssembly="AtlasControlToolkit"Namespace="AtlasControlToolkit"TagPrefix="cc5" %>

<%@dotnet.itags.org.RegisterAssembly="Microsoft.Web.Atlas"Namespace="Microsoft.Web.UI"TagPrefix="cc4" %>

Hi robpor88,

Thanks for bringing this to our attention. Does it flicker when loading, scrolling, or at other times? Could you perhapsfile a bug over at CodePlex?

Thanks,
Ted
