Last line is duplicated after submission

well, same problem here and there isn't much you can do..i believe it is the problem combining with <font style="BACKGROUND-COLOR:..."></P></FONT> because it isn't closed correctly(the <font..> tag) when in combination with <P/>.
For this reason i believe there isn't problem with firefox and mozilla which uses <br/> instead of <p/>. it also isnt problem with older version (i am using 2.0 beta version). the most effective thing to do is to use RemoveFormat function after using background color!
This problem also occurs when swiching to source mode and back. it duplicates strings every time user switches to source mode and for this reason it can be very unpleasant bug.
If there is a solution to this problem please advise.
Regards,

well, seems it isnt only background color, but also every other text property (also bold, font size,...u name it) when using copy and paste. try using "paste form word" command. still think that <p> is most disturbing.
ciao!

This also happening with me, and past as word dont work. We need past only as plain text to solve this bug.
