So my problem is over – I think – but do you think it would be a good idea to have a tool to check for invalid characters in NOTES given the rather severe impact of hitting one – if indeed this was the cause?
We do, which is why I would like to look further into the cause of this problem. It is possible it is server settings (security related) rather than kiwitrees.
Do you have a copy of the original NOTE you can email to me for testing?
