Version: (using KDE 4.3.3) Compiler: GCC 4.4.2 OS: Linux Installed from: Gentoo Packages I have just upgraded from KDE 4.3.2 to KDE 4.3.3. I have noticed the following regression: I always want to use KMail standalone. But in some cases, when a KMail window needs to open, a ontact windows opens instead. This happens when: 1) KDE starts up, and KMail tries to check mail on startup. In 4.3.2, there would be no other window except a KWallet prompt, which KMail uses to fetch new messages. In 4.3.3, both Kontact and KWallet come up. 2) I open a mail message. Together with the message window, a Kontact window opens. This happens only once per session, further opening of message windows does not open Kontact. 3) The same behavior as in 2) when composing a new message.
This has been fixed in the Akonadi-based KDEPIM suite.
