Hi there

From time to time, we receive this exception that is caught in our catch all My.Application.UnhandledException, resulting in a system exit:

Object reference not set to an instance of an object.

Any idea on why we receive this exception? It is intermitent, so I can't give you an example of when it occurs unfortunately

I found this issue listed in several direct trac incidents. It should have been corrected in version Are you using an earlier version?
