Version: (using KDE 4.4.2) Installed from: openSUSE RPMs Normally KMail is configured to reside within Kontact but if one opens Kontact while an email composer window is already open KMail is opened in a separate window. Clicking on Kontacts mail icon merely activates the separate KMail window. Also KMail stays open if one closes Kontact. How to reproduce: 1. Make sure no KMail, Kontact, Email Composer window, ... is currently open. 2. Click on some mailto: link on the internet and wait till the email composer window gets opened. 3. Start Kontact. 4. Now you should have a separate KMail window too that isn't integrated into Kontact albeight it should be.
