I have tried and tried but cannot find the menu item that gives "Keep Island".
When I do a fill, it does not appear on the right and I can't make it appear.
Any help gratefully received.
Thanks.
Oops! Sorry forget that I just found it!
For anyone else who finds the same thing, you have to right-click on the dotted outline that you first setup when selecting the area to fill.
Solved by time!
Brand new interactions and interfaces. 
Easy to use and quick to get started.
