Open east-tec InvisibleSecrets and click Options. In the Options Dialog Box select the Stealth Mode check box. Click OK. The program will disappear from the Start Menu also. To run the program again you must search the main EXE file and execute it (this is usually in the "Program files" folder where you installed InvisibleSecrets). You can always make them visible again by unchecking this box.
You may also hide the tray icon and menu. The tray program will still run in the background, because it remembers the cryptboard and handles the locker's hot-key event.
