After editing a diagram, I found that what looked like a spurious sequence flow had got onto the diagram.
The offending flow is coming from the Send task. This flow can’t be selected, and so can’t (as far as I can see) be deleted. Often when I’ve seen this sort of bug in other Windows programs, if you scroll the offending object off the screen and scroll back on again, the object has disappeared - but this doesn’t work in this case. If I print the diagram, it prints the offending flow. It seems that VA really does think this object is there, but won’t let me delete it.
Why has this object appeared? How do I get rid of it?
