[MacPerl] Mac::Controls::TrackControl()

[ajf@afco.demon.co.uk (Alan Fry)]

TrackControl() works as expected with two arguments, and with 0 or -1 as
the third argument, but I cannot get it to work with a procedure as the
third argument. Offering a subroutine &myProc (or \&myProc) gives rise to
the error:

  Mac::Controls::TrackControl: Last argument must be procedure, 0, or -1

Can anyone help?
