We just updated from 5.0 to 5.1, install went perfectly as usual

However, I can't find where to see the PTR / rDNS entries in the log viewer. I looked for hidden columns, options, settings, can't seem to find it,

Or does this reference the button you see after double clicking one entry, the "lookup" button?

I was hoping the IP Address column might now have dns hostnames in there, or a corresponding new column

@Bryon: "Or does this reference the button you see after double clicking one entry, the "lookup" button?"

Yes. ORF will not resolve the IPs automatically, log the results, and present the resolved names in an additional column: the reverse lookup can be triggered only manually by clicking "Lookup".
