In IC5.0.33, when selecting menu "Edit / Library Path..." from Library Manager's main menu, an error dialog displayed:
TITLE of Dialog: Read Only File
Messages: The file "/home/icdesign/cds.lib" is not edit locked.
Then the "Save" item under Library Path Editor's "File" menu is greyed out.
In the library path editor window, go to (I don't have IC50 with me now) Edit (?) manu, there should be a "Unlock ..." (?) like command (Just browse through all the manus), just select that command.
