Version: 3.5.6 (using KDE 3.5.6, Debian Package 4:3.5.6.r1.dfsg.1-1 (4.0)) Compiler: Target: i486-linux-gnu OS: Linux (i686) release 2.6.18.6-slh-up-1 Sure switching applications and desktops with the mouse wheel is a very nice feature - as long as you use a real mouse wheel. But it can be a pain when you have to use a touchpad and hide the kicker because of a small display (notebook). It often happens that by activating the kicker the windows or desktops are switched accidently. Therefore it would be of great help to be able to disable that mouse wheel switching optionally when using a touchpad. By now it seems only possible to enable/disable the switching of desktops with the mouse wheel over a non-used place of the desktop. Please add that option to kicker too.

Kicker is currently unmaintained, you can look to your distribution for help, however.
