 I have a connection on site explore. It keeps bugging out with "session
 lost". So I click the layer and then the little red X. It asks me to
 delete it and I say "yes". This then gives me the below error.



 Object reference not set to an instance of an object.

 System.NullReferenceException: Object reference not set to an instance of
 an object.
