Internet Explorer closes all browser windows after closing a vector map

PROBLEM
When closing the window for a vector map you get the error message



If you click on the click here link at the bottom you get this Error signature



Click Close then click Don’t Send.
At this point all your Internet Explorer windows will close.

SOLUTION
This is caused by the Google Toolbar in Internet Explorer. Go back to www.crsdata.net and click on the # blocked button in the Google Toolbar and Allow Site Popups. You should now see a button that says Site popups allowed.
The next time you close a vector map an error should not appear.
