[kubuntu] Klipper doesn't function across programs

view story

http://ubuntuforums.org – Hello My klipper doesn't allow me to copy text from one program to another. For example if I want to copy a url across from my browser into kate, I copy the text out of the url, then I right click and paste into kate and instead of pasting the url into kate the last thing I copied in kate is then repasted into kate. Any help in solving this problem would be greatly appreciated. (Hardware)
