Mark, before we can tell you the cause of trouble, we need to know the issue.
Without direct access to your installation, we can only guess, based on your description, what the issue can be. We are not prophets.
It can be a bug, but it can be very well a user error.
To rule out the user error I have asked you for:
a) screenshots. This is the most helpful thing that you can provide.
b) clarification on exact steps, plus terminology. Some of yours statements sound rather incorrect.
To say something is a bug, once we confirm it is not the user error, we need to verify that bug somehow. Then it can be added to the tracker and fixed. So far no one else jumped in to say that they had the same issue, so if you want help/fix, you need to provide very clear review and scenario for developers to replicate it.

p.s. I see that you have already opened the Tracker ticket, which does have a much better explanation. I would advise you to link to the tickets if you post in the forum, therefore no ones time would be lost on basic troubleshooting.
