I am new to PL/SQL Developer. I pressed the F1 key and tried to set up my HTML Help. I did something wrong and now everytime I press F1 or go to the Help HTML Manuals menu item I am locked up. I can't find anyway to reset this.
Perhaps you can go to the Books subdirectory in the PL/SQL Developer directory and delete all files? Maybe the indexed files are on a network location that is no longer accessible.
