This morning, a colleague experienced a new twist on the leader line-breaking saga:
He ticked the requisite box to ask SW to break a leader line and clicked the green tick.
No break appeared, so he selected the dimension again - there was no tick in the 'Break Leader Lines' box.
This sequence of events was repeated several times until he finally gave up in disgust and said I (the checker) would just have to live without the break!
Any suggestions as to why this could be occurring?
