at first: BPVA is a great application - I like it.
One problem: The option “line jumps” doesn’t work for me and I don’t know the reason, because in the preferences I have activated this option.
Is the problem sitting in front of the monitor?
My System: Mac OS X 10.6.2
Thanks for your post. The line jump setting at Tools > Options > Diagramming > Connector takes effect to the new diagrams only. For existing diagrams, please right-click on the diagram and select Connectors for choosing the desired line jump (as shown as attached image).
Hope this solves your problem. Please feel free to ask if there is any further question.
