there is a problem with the drop down list ("Search in: ") in the FileChooser dialog of the button "Add JAR/Folder" at
the Library Manager. This drop down list should display the file system tree but it always shows at most two items: the
desktop and per default the "My Documents" folder. So you cannnot browse in the drop down list, you have to select
desktop to access the file system and make your selectionsn in the list area underneath.
by the way, I also had this problem with Netbeans 6.0.1
