Ah, I guess that's the difference between KDE2 and KDE3 :) Fair enough...

On KDE2, it also shows a box with only a "close" button. I think you mean
to have Yes and No buttons?

yup, you're right. And something I most recently learned: you can do it

command & sleep 30; kill $! 2>/dev/null

By the time the shell evaluates the $!, it will already contain the PID of
the backgrounded process...
