When you have a list of items that have numbering turned on and one of the 
lines of numbered items contains a hyperlink and you attempt to change the 
font size, (or other attributes  such as bold, italics, underline), the font 
size, (or other attributes), of the numbering on that line do not change. 

How to create.
1. Make several short lines of text.
2. On one of the lines include a hyperlink. http:\\www.something.com. Either 
cut and paste or use the insert hyperlink from pull down menu.
3. Highlight all the text with the cursor and click Numbering On/Off in tool 
bar.
4. Highlight all of the text with mouse and change the font size by pulldown 
in tool bar.
5. All of the text will change size EXCEPT for the number on the line with the 
hyperlink.
6. For other attributes do the above again by selecting all text and using 
another attribute such as underline. All text will be underlined except for 
the number on the line that contains a hyperlink.
  
If the above numbered list were typed in and the font size changed, as 
outlined, then the number 2. in the above text would remain the same and all 
the other text would be changed to larger (or smaller) font.
Seems to happen with all fonts but only tried a couple.

Thanks
