When I enter an email address into a cell in Calc it automatically gets formatted into a mailto: link. Clicking on the cell in Calc 126.96.36.199 (Ubuntu 12.04 - Gnome3) results in starting a new email to that address, but clicking on the cell in Calc 188.8.131.52 (Mint 16 - Cinnamon) does nothing. Both machines are using Thunderbird for email.
I can get the desired functionality by ctrl-clicking, but the inconsistency is confusing for new users (Excel behaves as 184.108.40.206). What could be causing this?
Also the formatting for the email link is a dark grey background with dark blue text (in Mint 16), making it difficult to read. Is there a way to change this?
