FM 11 Line numbering bug

[Rob Shell]

******BUG******
There seems to be a troublesome problem with the new line numbering option
in FM 11.
If you use line numbering and use a side head for paragraphs, the text to
the right or left of the side head disappears on the screen. The print
output via PDF is fine, but the GUI is broken. 
I am very glad that Adobe has included line numbering as all lawyers use it
and therefore a new market share, previously dominated by WordPerfect 10+ ,
is available. 
However, we must get it right.
Concise problem statement:
Steps to reproduce bug:
 1. Fill a paragraph with text
 2.Create a sidehead with text say 2012
 3. Request line numbering
 Results:
 Expected results: Text to the right or left of sidehead disappears on
screen. This bug does not affect the pdf creation
