I have a numbered list like:

1.0 Excel 2010 1.1 Introduction to Excel 2010 1.1.A. A general overview of Excel 2010, geared towards beginners 1.1.B. There are 3 videos in this series

I put the cursor at the end of the last line on 1.1.B and hit Enter. The next line should begin with 1.1.C but nothing appears when the cursor returns to the next line.

Another example, if I put the cursor at the end of 1.1.A and hit enter, I should get a new 1.1.B and the original 1.1.B should be renamed to 1.1.C. After hitting enter, a new 1.1.B doesn't appear and the previous 1.1.B drops all the way to the next page.

So the next bullet number that should come up doesn't come up. I tried Microsoft Fix It to reset the Registry and that didn't work either.

This is very frustrating. Does anybody know how to fix this?
