Actual Results:  It does not print: 
   Find more information about java plugin at Sun Microsystems.

Expected Results:  After a list of table, it should print something like:
  Find more information about java plugin at Sun Microsystems.
But it does not print these lines. To my suppurise,Netscape can print these 
statesments
Using Mozilla binary 2001012504 on WinNT. WORKSFORME - I see the text

      "Find more information about java plugin at Sun Microsystems."


Xiaobin, what Mozilla BuildID were you using? And what do you see
when you go to Tasks | Tools | JavaScript Console? Hit "Clear" there,
then load the page, and look in the JavaScript Console again.
Do you see any errors there? 


When I did that, I saw an "unterminated string literal" error.
I went back to the HTML and fixed all the broken lines, and then
everything worked fine. I will attach the HTML file below -

Xiaobin, if this is still a problem for you, please reopen the bug.
But I am having no problem seeing the message

   "Find more information about java plugin at Sun Microsystems."


on both the testcasese above. Note: without cleaning up the broken
lines, NN4.7 did not print anything, either -
Status: RESOLVED → VERIFIED
  I don't know what's wrong with my system at that time. Now it works pretty 
well.

   Thanks!
