I for about an hour I seem to have lost the cc field when I choose 'reply to all'. All it showed was a hyperlink to 'show bcc'. I was able to get it back by visiting all the options pages and the zd setup page. Then suddenly it came back.

I think I made the cc field vanish by selecting the sole cc entry in one email, and hitting ctrl x (cut shortcut) to copy the entry. After that I believe the cc field vanished.

Anyone else seen this?
