Ivan The khelpcenter icon in the task bar does not open the help (konqueror showing help). I am using the latest upgrade 2.0.1 from Friday morning on a machine with Potato. khelpcenter works if you type "khelpcenter" from the konsole, and the icon in the task bar works if you change the name of the program in the preferences menu of the icon, from "khelpcenter" to "/usr/bin/khelpcenter" Pablo.
