Looks like I can have events with a plain label, but one that is joined to or has been disconnected from a textbox can't.
Surely that can't be right!!
Need to investigate this. Going into pedantic mode now.
Thanks for taking a look at this plog.
EDIT:
Another messy fix, but not quite as bad as my original idea.
Select all labels on the form (not the textboxes) then copy & paste.
Move labels so they partially overlay the originals
Press CTRL and select topmost original label then align to right and top.
Holding CTRL click 3 times the topmost label that you aligned to (deselecting the copy and original before reselecting the copy)
Amend the caption to [press spacebar]
Then delete the space from the caption so all copy labels are now blank - events can now be assigned.
Told you it was messy
