I have some students who will probably need to use some nonstandard (for
the Mac, that is) interactive techniques like popup menus, cursors that
don't track the mouse, and the like. I vaguely remember seeing something
called TrackPopUp which I think was a library of routines that could be
bound into a Pascal program. (This project will be done in Lightspeed
Pascal - not my idea, but things that don't fit that environment are out).
Anybody got stuff like this? I don't want them reinventing wheels.
No flames about the Apple user interface guidelines, please. There are
several good reasons for ignoring them here.

PopUp Menus are implemented in the current System files. You'll need the
newest release of LSP so that you can call the routine. The routine to
call is:
function PopUpMenuSelect(theMenu:menuHandle;
top,left:integer; item:integer):longint;
Simply get the Menu first, don't install in menubar, in the above call you'll
pass it it's menuHandle, top and left are the coordinates of the upper left
corner of the menu, item is the item number that should start out selected.
If you haven't got the latest LSP update, you can use an inline and define
the above function as trap $A80B.
Disconnecting the mouse from the cursor is something Apple hates to see with
a passion, so there isn't any support for it.
