What should you do when this dialog appears ?
You should use the mail error report button to ensure that all relevant information is sent to technical support.
Sending a screenshot of the closed dialog, as it appears above, supplies no useful information to technical support.
If you cannot use the mail error report button because you do not have an internet connection, and if you can only send a screenshot, then you should open the dialog by clicking on the show error report button and select the call stack panel (as shown on the right) before taking a screenshot.
Once you have generated a screenshot, you can send it via email to technical support.
