PDF Print Monitor: How can I disable tray icon menu item "Options"


My Environment: Windows7 32-Bit:

I've found a registry key to hide Menu "Options" when PDF Print Monitor shows up ==> OptionsEnabled and OptionsVisible set to 0

So far so good, but as soon PDF Print Monitor is minimized  the Tray Icon Menu shows "Options" as a Menu Item again.(Bug Or Feature ?)

Does anyone knows a possiblity to hide Or disable the TrayIcon Menu item "Options" ?

Thanks in advance for your help
