It appears that the VirtualEarthOverlay has a map click event in the backgroup above and beyond Thinkgeo's map click.
the problem I am having is that I kept getting a "null is null or not an object" javascript errors on my click events ever since I started using VirtualEarthOverlay. I have a click event assign to my map
<mp1:map id="Map1" width="800px" runat="server" height="600px" onextentchanged="Map1_ExtentChanged" webconfigregistermode="Manual" mapunit="Meter" borderstyle="Solid" backcolor="Black" borderwidth="1px" onclick="Map1_Click" style="margin-right: 0px"></mp1:map>
After troubleshooting my click event, I decided to disable it altogether, so I remove the OnClick form my map definition. However I still get the javascript errors when clicking on the map.
It also appears that the errors are being thrown by Virtual Earth

I realize that this is not your product but there should be some way to disable the click event on the virtual earth layer and only use the ThinkGeo map click event? Any idea?
