Hi James,
Normally the frame around the VC is Green or Yellow.
What does the pink surround signify - At a guess I think it means I have done something it does not like :)
Best wishes.
it represents an error of some kind, though not necessarily serious. It could be something you did or it could be me...
usually it means one of the actions in a macro failed. If it was the last action triggered, you may be able to see the error in the results tab.
anyway, as long as everything is working normally I wouldn't worry too much about it.
