I am grateful for the time you've spent on this problem but I think, like me, you like a challenge.
I worked on the database last night without a single issue. It was a pleasure to be able to do that, but that only means I've been lucky.
I will continue to develop the database and look out for any more problems.
As far as I can tell, I have restored the db to the state before I submitted it, i.e. API working and code as original.
If it re-occurs then I will think about changing the MainOptions form design to simplify its operation.
In the meantime - thanks again for your input and time. And Pat's.
