That's because the bitmap referenced above is incorrect.
mozilla actually uses a 32x32 bitmap.
A working example is below.

It's actually due to a reappearance for a while of an old bug I think?
http://bugzilla.gnome.org/show_bug.cgi?id=103616

I still have a couple of questions:

1. Is there an easier way to set left_ptr_watch instead of copying the mozilla bits?
2. Is there a way to create a Pixmap of depth 1 using pixmap_create_from_xpm_d

thanks,
P�aig.
