Sometime ago, the lines in my relationships disappeared.
I have been too lazy to do anything about this but I guess it may be serious.
What could cause this to happen and how can I get them back apart from going through the squiline tables and redrawing them - and getting some wrong
I tried to delete a table today and it wouldn't allow me until I had deleted the relationship first yet I can not see the table or the relationship line.
Appreciate any guidance.
