When I started the computer, a small window (a box with no title bar) popped up saying "kupdateapplet: New Software updates for your system are available. More..." I clicked on it and nothing happened. I then clicked on the kupdateapplet to have it check and it found no updates. And now the window won't go away and it's on top of everything. I've tried to look for it in "ps -A" but have no idea which one it is. Can someone help me kill this window?
