Hi, I started asking about this in a previous post but I realise I haven't solved it (as I thought) so I'm starting a new one.
I upgraded to RH10 from RH7 and something has gone wrong with my TOC.
When I open RH the TOC is empty and when I check the .hhc file it's empty although the backup is around 80KB.
So I create a new TOC and copy it from either that backup or from an earlier .hhc file. The TOC appears, looks perfect and I can edit it fine but whilst I'm looking at it in RH I can see that the .hhc file is still empty. Next time I close and re-open RH, there's no TOC.
I should clarify - the TOC exists in RH but is empty.
What happens if you create a new ToC and auto-generate it - does it stick around once you save & reopen RH? If so, then I would suspect there's something amiss with your "legacy" ToC and you may have to recreate it from scratch in RH10.
Yes, a completely new TOC seems OK so I guess that's the answer.
