Have you ever noticed how Word tries to be 'helpful' if you start to type a numbered list?
Word takes over and changes the formatting
The same happens if you type an email or website address - Word turns it into a blue underlined hyperlink.
If you don't like this interference from Word do this:
1. Click on
2. Select (down the left hand side)
3. In the left list click
4. At the top right click
5. On the window that pops up click the tab entitled AutoFormat As You Type so you see this...
6. Remove the ticks as shown above and then click the OK button (click OK again after that)
