long text (without line return) is troncated in the print whatever the browser

hi !

In the webmail :

I have many mails where people writes long text without carriage return nor line feed, neither line return. Just pure text like Proust!
I have no way to print this mails !
I tried every position, every browser and zimbra always troncate the content !

i guess zimbra do not replace &nbsp by classical space for printing whereas it does right for display the content.
Or maybe there is an option i didn't see ? I use zimbra 6.0.10, maybe this bug have been fixed in last release...?

thanks for help

or maybe the overflow property of the CSS is not good (Hidden instead overlow or fixe height...)
