HTML source when composing mail

[lizat]

Dear Cubes,

I can see incoming mails OK but when I compose a reply I get the html source. I have no idea what I've done but did recently upgrade to latest Roundcube version. Any ideas if a plugin could be causing this or what else?

Thank you...................... liz

Ok so this happen in Firefox only, IE is ok. I am using the compose plugin so I write in a new window, haven't checked but I think it's that
