I used outlook on 6 nov 2013 and I had a spell check in the top blue bar. When I used it 11 nov 2013 it had vanished. I have a standard Vista home basic sp2 running on a toshiba satellite computer.  I have completely down powered the compter to reset any problems there but this has not cured the problem. Msft has automatically loaded some patches in this period. Is this the problem?

Thanks Ken Whyborn
