I do want to add by saying that the <enable-flash-desktop>false</enable-flash-desktop> is not always the reason that flash menus will not work. If it had originally said true or if changing it to say true did not work, then you must search your phone using FAR and go to TPA\PRESET\SYSTEM\DESKTOP\FLASH. Inside this directory there is sometimes a file named "DisableFlashDesktop". DELETE THIS FILE. Once done, your phones flash menus should work.
