DropDownExtender positioning error

If the target control of a DropDownExtender is used in a control or div tag that has absolute, relative or fixed positioning the dropdownlist will incorrectly position below the target control.

The actual context menu will be displayed in the correct place but the hover panel that looks like a standard dropdownlist control will be displayed incorrectly. See the following link for more information and screenshot of the problemhttp://www.codeplex.com/AtlasControlToolkit/WorkItem/View.aspx?WorkItemId=10075

Here is an arbitrary example. The real problem is when this control is used in third party grids that make use of relative positioning of some of their outer elements.

Has anybody else encountered this problem? Anybody know how the DropDownExtender javascript/CSS could be updated to correct this issue?

Example code

<div style="position:fixed">
<asp:Label ID="Label2" runat="server" Text="Select action"
Style="display: block; width: 100px; padding:2px; padding-right: 50px;" />
</div
<asp:Panel ID="Panel1" runat="server" CssClass="ContextMenuPanel"
Style="display :none; visibility: hidden;">
<asp:LinkButton runat="server" ID="LB1" Text="Mocha" CssClass="ContextMenuItem" />
<asp:LinkButton runat="server" ID="LB2" Text="Java" CssClass="ContextMenuItem" />
<asp:LinkButton runat="server" ID="LB3" Text="None" CssClass="ContextMenuItem" />
</asp:Panel
<ajaxToolkit:DropDownExtender runat="server" ID="DropDownExtender1" TargetControlID="Label2" DropDownControlID="Panel1" />

I'm having the same problem. It started after installing the latest build. The problem is not limited to 3rd party controls. Even the slightest modification of the Ajax dropdown example to position the target element creates this problem

Example code: -- same as dropdown example in the AJAX Samples: (For the sample, the problem occurs with either "relative" or "absolute")

<divstyle="position: relative"><asp:LabelID="TextLabel"runat="server"Text="Hover Over Me"Font-Names="Tahoma"Font-Size="11px"Style="display: block; width: 300px; padding:2px; padding-right: 50px;"/></div><asp:PanelID="DropPanel"runat="server"CssClass="ContextMenuPanel"Style="display:none;visibility:hidden;"><asp:LinkButtonrunat="server"ID="Option1"Text="Option 1"CssClass="ContextMenuItem"/><asp:LinkButtonrunat="server"ID="Option2"Text="Option 2"CssClass="ContextMenuItem"/><asp:LinkButtonrunat="server"ID="Option3"Text="Option 3 (Click Me!)"CssClass="ContextMenuItem"/></asp:Panel><ajaxToolkit:DropDownExtenderrunat="server"ID="DDE"TargetControlID="TextLabel"DropDownControlID="DropPanel"/>
