Hi. My experience using Netscape through Thunderbird mail has been that 
sometimes the attachments won't forward correctly using the Forward 
buttons on the tool bars. The only way I can be sure TB forwards 
attachments right is to click Messages, Forward As, then Inline. This 
has worked for me to be sure. I must say the TB works better than 
Netscape in this area.
