Exception

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?

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

Thanks,
