lets say the user had been resizing the window without any modifier keys
pressed, but then realized what s/he really wanted was to resize in only one
dimension or to maintain the window’s aspect ratio, so now s/he presses either
shift or shift and control. i would like to be able to resize the window at
this time to show the proper effect, but i can’t do this until the user moves
the mouse AFTER changing the modifier keys.

two immediate comments though:
in the override you suggest, i will have to “or” in the
NSFlagsChangedMask to make sure i get the changes as the framework’s event loop
may (i don’t know) be only looking for mouse down or mouse moved events. and
the framework may be using -nextEventMatchingMask: instead of
-nextEventMatchingMask:untilDate:inMode:dequeue:
i will experiment and report back.
thanx for the suggestion,
