Since not all versions of User Input Emulation tool support this request and not all guest OS can supply required functionality, use TIS uuid TIS_UID_UIEMU_GUEST_CROSS_CLICK ("parallels.UserInputEmulation.guest.cross.Click") to get status of that feature. If this uuid is in active state in TIS database, this function can be used.
