Exception

[John McLean]

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

Cheers,

I found this issue listed in several direct trac incidents. It should have been corrected in version 5.1.1.0. Are you using an earlier version?

[John Barrie McLean]

We currently have version 5.1.0.51 installed, so I'll get the latest version.

Thanks,
