We are having this issue too. I called MYOB support, they said the Development team know about it and are working on it, gave me case number 02242811
I am amazed the dev team are taking over 3 months to fix such an integral part of the system that seems like it would be at most a 1 day fix. Possibly 15 mins. Really not good enough, but what can we do other than complian and wait.
I wish it were possible to unmark the "solution." Welcoming people to the forum and telling them to clear their browser cache is not a solution. Has this worked for anyone?
