Version: (using KDE 3.5.9) Run composer, turn "reply to" field (menu view), on the right you will see button with "..." label. Move mouse over it -- nothing, no tooltip. Click on it -- nothing. Button without label really, without meaning, non-working. Since it only takes space, please remove it.
Confirmed, the button is useless. (in KDE4 it has been removed ^_^ )
Thank you, so I close this report.
Even if in KDE 3.5.9 is still present?
Yes, of course, after all KDE4 is next version of KDE.
Ok, I agree :)
