Version: 3.9.95 (using KDevPlatform 0.9.95) (using 4.3.1 (KDE 4.3.1) "release 1", openSUSE Factory) Compiler: gcc OS: Linux (i686) release 2.6.31-rc9-7-default When you change tab for the first time (Test-debug-code) it minimizes the window. It is really on the first time that the bug appears, it still works once resized on each tab, even if you restart your computer.
