Create Region not working as SS10.

Using CE16 I have found that Create Region now doesn't keep the previous options set, but SS10 does. If I set the option Fill Type to Opaque it works OK, but if I go out of the tool and then come back to it Fill Type has reverted to None. This is a pain as I need to remember to change to Opaque each time. This is a new bug as far as I can see as I'm sure it worked OK in U15.
