OK, does seem to be fixed now. I spent a disproportionate amount of hours last week finding a workaround to this problem which I will now have to unpick to get it back to how it was originally.
Do you have answers to the other questions I asked above regards where these bugs are recorded and how you keep customers properly informed (Or indeed informed at all) about them?
