Deleting A Card

[Andy Calloway]

Hiya all,
 
I'm still just playing with RunRev, but I've come across what appears to be
a problem. I created a mainstack and added seven cards (just running through
the tutorials). I've now come to do something proper with them but I can't
delete any of the cards.
 
I move to the card I want to delete, choose object-> delete card, say 'yes',
but nothing happens. A bug or am I missing something peculiar to RunRev?
 
Andy.
