<p>A friend of mine has embedded a google earth plugin into a C# user control. All works fine but when you close the window we recieve and "Unspecified Error" with the option to continue running the scripts or not. From our tracking it down it appears this is being cause by a script that google is dropping onto the page. Any ideas?</p>

We have now tried this in both IE and FF. Works fine. Any ideas why the error only comes up on close? can we somehow disable it? here is our code.
