Sorry to be so long – I forgot I had to drive in to town to see my dentist!
I have a working theory… I need to consult Steve though. But getting close!
I think there is a small flaw in the code (already fixed for the next update) but this is being exacerbated by one of your settings which I think is incorrect.
The forum ‘Off Music Topics’ has assigned the ‘Regulars’ user group with the ‘moderators’ permission set. Would I be correct in thinking that for this forum – as with the others – that ‘Regulars’ should be paired with ‘Standard Access’?
I think if you change that then the problem should be corrected. This situation, coupled with our error in the code is almost certainly responsible.
And now I am eager to know if this is it!
Excellent and with our fix in the next update if that happens again it wont manifest itself in the same way. That was a good find. Thanks for your patience and help in tracking it down.
Oh yaaaaaaaaaa 
I’m happy that I am not just pestering you guys all the time for nothing. LOL
jk….
