Version: 1.12.1 (using 4.3.00 (KDE 4.3.0) "release 152", KDE:KDE4:Factory:Desktop / openSUSE_11.1) Compiler: gcc OS: Linux (i686) release 2.6.27.25-0.1-pae In KDE3 at least when I clicked on accept or decline the mail got moved to trash automatically. Now with KDE4.3 when I click decline on an invitation, the mail stays in my inbox.
There is an option which controls this, under Misc->Groupware. Is it enabled?
Shame on me, I did not know about that option and it was disabled... sorry for the buzz.
