[PyMOL] wheel slab doesn't work (pymol 1.0)

[Xuewu Zhang]

Hi, I compiled the svn pymol version 1.0 on a MacBook (using python in
fink). Everything worked perfectly, except that "wheel slab" of my three
button USB mouse doesn't work. It works fine in Macpymol, so the mouse
itself it functioning. Did I do something wrong or it is a bug?
Thanks,
Xuewu
