Excuse the double post but I've just been and had a play with a few options to try and solve this and I have made it work, for me at any rate.
Assuming you are using the "bank/patch change" command from the "Insert" menu, change the "Bank Select Method" from "Normal" to "Controller 0" and hey presto bank and patch changes. Whether this is because of the way my MIDI set up works I have no idea, but it's definitely started working for me. Hope it does for you to..
