Version: 4.2.3 (using 4.2.3 (KDE 4.2.3), Kubuntu packages) Compiler: cc OS: Linux (x86_64) release 2.6.28-11-generic I have a first tag, let say test1, and a sub-task test2. If I click on test2, and change completion from 0 to 10% for example, after validating, it is displayed like a normal task, no more in a tree under test1...
which resource/calendar are you using? akonadi, local ics resource, remote, etc?
