	You should hide your mouse before doing an objc_draw().

		Why's this commented out?

	Well, if this ain't it, you must be mixing graf_mouse() and
some other version of mouse on/off like v_show_c() v_hide_c(). When you
use these two functions, you should pick one and stick to it, don't
mix them, or GEM get's confused...

	Also, if you forgot to hide your mouse _anywhere_ in the program,
you can end up with problems like these.  AND if you don't reset GEM after
confusing it (i.e. you're in a shell and don't exit to the desktop) GEM
can continue to be very confused and you my never be able to see that
you fixed your bug :-).
