Selected menu items in a custom 'MDEF' resource do not flash correctly
due to a bug in the Menu Manager. This Technical Note describes the problem
and explains how to make your 'MDEF' flash correctly.

Not on the Menu
There is a known bug in the Menu Manager's interface to custom 'MDEF'
resources that causes an item to flash incorrectly if its corresponding menu
record contains no text. If there is no text in the the chosen menu record,
the Menu Manager neglects to call the menu definition procedure multiple times
with mChooseMsg, and the corresponding item does not flash. If there
is text in the menu record, the Menu Manager calls the menu definition
procedure multiple times to flash the menu item.

No Substitutions Allowed
Until a corrected version of the Menu Manager is released, you can make your
custom menu items flash by adding a dummy text menu item in the menu record
corresponding to each item in your custom 'MDEF'.

For Example...
When using a Macintosh with color, notice that items in the Finder's Color menu
(other than the first one) do not flash. Edit the 'MENU' resource
(id=16) in a copy of the Finder. After menu item "x" add menu items "b," "c,"
"d," "e," "f," "g," and "h" (or other legends of your own choosing) to
correspond to the additional seven Color menu items. After rebooting with this
edited Finder, selections from the Finder's Color menu should now flash
correctly.
