Version: 3.2.3 (using KDE KDE 3.4.3) Installed from: Fedora RPMs OS: Linux When editing a PHP project in kdevelop, selecting the PHP tab (the browser preview one), and then clicking the close tab button closes the last selected tab instead. It should behave like konqueror, in which you can close the tab, and middle clicking on links in that browser tab opens up new browser tabs.
The PHP tab cannot be closed in 3.4.
