UDPATE!

Figured out how to fix this problem. 

Just don't use bullet lists. I can make lists in Keepnote with out bullets. 
Tabbing works fine. 

Fixed.

Hmm.  Somehow a strange nesting of bullet lists occurred (that should never 
occur) that keepnote was not able to save.  Does this always occur when you 
create bullet lists or only rarely?  If you could figure out the steps needed 
to recreate this bug, I can try and debug it.  Thanks.

I'll have to try it when I have down time. At the moment I can't afford to have 
Keepnote crash. Using for lots of stuff.
