Find the program executable for the program you want in Quick Launch. RIGHT-click "drag" the executable icon to the desktop and when you release it, select "Create shortcut here". Once that's done, simply do a normal left-click drag of the shortcut to the Quick Launch toolbar.
Hope this helps.
I have Windows XP Pro, sp3.
How can I make an icon on the Quick Launch toolbar? It's easy to delete them but I don't know how to make them.
