hello!
see my screenshot. after sending mail, the "Sending Mail..." overlaying text is not going away!

Maybe the best way to improve it is to go to the wiki web page and create a new ticket (http://trac.roundcube.net/newticket)
just downloaded and tryd 0.1.1 - and still the same!
I need a newer version beaucse PDF downloads not worked, with 0.1.1 this seems improofed, but mail sending is horrible.
on the wiki page
"Forbidden
TICKET_CREATE privileges are required to perform this operation"
You must understand that I not plan to become a developer, I just want to use a working roundcube. It should be enough when I point out a enormous bug like this.
