      Well, it moves a little slowly, but the entire game moves a little =
=20
slowly, and that's OK ;) I'll record my old function (just in case=99), =20=

and see about a CoreGraphics-based version.

      Hmm, that version doesn't seem to handle the mouse as well; I see =20=

what you mean about GetMouse acting slowly. My code for Carbon =20
mouse_idle() is at the end of this email - to use it:
      1- "#if !TARGET_API_MAC_CARBON" out the original mouse_idle() =20
function
      2- #if out the set_mouse_position() prototype and function.
      3- Make get_mouse_position() call GetMouse() #if we're in Carbon
      Try it and see if the results you get feel any different. It =20
certainly seemed smoother to me, even if it wasn't really a good =20
solution. Perhaps the problem is with CGWarp...() instead?

      Oh, and "way back when," I used the keyboard too. Except that "way =
=20
back when," Kindergarten was a challenge, and that's not a memory I =20
like to remember.
