Version: (using KDE KDE 3.5.5) Installed from: Ubuntu Packages There is no option to configure the behavior of the mouse wheel in the actions sections of the task bar configuration dialog, and none on the configurable items have a do nothing option. Many people have mouse wheels which are too easy to move by accident, making assigning an action to the mouse wheel for the task bar undesirable.
Kicker is no more mantained and all bugs/wishes will not be fixed/implemented in KDE3. A list of the most interesting/unresolved issues which is still valid for KDE4 has been created. Before reopening old kicker bugs on KDE4 Plasma, please try the new KDE 4.3.1, check the current behaviour and, only if you find new bugs or if you need a particular feature, open a new bug report. Remember that KDE 4 is a full rewrite of KDE 3 so some old features will not be re-implemented because the behaviour has be changed a lot on some sides. Thanks for the comprehension and enjoy the new KDE 4! -- FiNeX & D. Andres
