ZoomText stops reading after sending an ACCESSIBLE_STATE_EVENT
with SELECTED as old value.

A MENU may have the state SELECTED, namely when the corresponding
submenu window is opened. If the window is opened, the MENU sends an
ACCESSIBLE_STATE_EVENT with SELECTED as new value.
ZoomText reads e.g. 'File menu opened'. Then the first MENUITEM of
the MENU is highlighted. Therefore the MENUITEM sends an
ACCESSIBLE_STATE_EVENT with ARMED as new value.
ZoomText reads e.g. 'New'. When the window is closed, the MENU changes
its state from selected to deselected. Therefore an
ACCESSIBLE_STATE_EVENT with SELECTED as old value should
be sent. ZoomText should read e.g. 'File menu closed'. But this
event stops ZoomText from reading the other menu items. Only after
a new ACCESSIBLE_STATE_EVENT with SELECTED as new
value is sent, ZoomText reads the text in the newly opened submenu
window.

MT: Work around is that we currently don't send these events on windows.
Must be fixed in ZT anyway, but they need a special dll from us for verifying 
this
