This is a plea for help. I'm in the midst of porting some software that uses
popup menus extensively. I'd like these menus to have the semantics of the
"rightMouse" Application menu - i.e. on mouseDown the menu pops up at the
cursor location, the user then drags the mouse to the required menu item
and then releasing the mouse button both selects the item and hides the menu
again. I have no difficulty creating Menu objects with items (and
submenus etc.)
and causing them to appear at the cursor location:

	[menu MoveTo:x :y];
	[menu makeKeyAndOrderFront];

However, I've not been able to reproduce the semantics I want. The menu remains
visible until explicitly closed by the Application via:

	[menu close];

I've tried using [menu rightMouseDown:&event]; and that appears to ignore the
"menu" id it is given but only pops up the main application menu (it also 
doesn't appear to track properly, but that's probably finger problems on my 
part). Failing this, I've tried to make my menu appear with the close box
visible (by setting some of the menuFlags) but that doesn't appear to do
anything either. Any (constructive!) suggestions would be welcome (I know what
I'm trying to do violates the NeXT interface guidelines, but I'm trying to
compromise between those and what this software is built around).
