An Example: I start K3b which has one of these extremly nice (*g*) KDE-Panel-Icons which is displayed in a Window (hmmm...hoefully support for them will be finished in time :) But no matter what I do it doesn't get Focus. When I click on one of the Buttons in the Title-Bar they get highlighted as expected, but like the Window has Focus. So the trick is to say not every Window you can click on has to have focus or every window you can click on has to get focus.
With "panel icon" you mean a systray icon? Support for the KDE systray protocol has been added recently, see http://lunar-linux.org/pipermail/xfce4-dev/2004-January/009265.html
Dunno know what you mean by that, but not all apps are focusable (try xclock) As for the button showing as hilighted, yes, that's true. I don't see any bug there. Olivier
KDE systray now supported, so bug is now irrelevant. Olivier.
