2 - When i add a program to my KDE start menu (like firefox) sometimes i get two applications running. One is the actuall program the works, and the other is the same program only it keeps on loading and doesnt load at all, about 30 seconds later it closes. Any tips?
Ignore that. The effect takes place. Open firefox, then open an html document thats on the desktop or a place like that with firefox, you'll see that it opened in the existing firefox window, but it shows as if its loading something.
Basicly instead of openning a new instance it "tells" the existing instance to open a new window or just load the webpage in existing window depending on how you have set it up.
