Creating & Using a Custom Cursor?

[Sarah]

I found that the colors had to be quite specific. You need an image 
that uses three colors: pure black, pure white and something different. 
Draw the cursor in a 16 x 16 image, using black AND white and then fill 
the background with color 3 and make it transparent. It might be easier 
if you import one of Rev's cursors from the image library, then trying 
altering it rather than creating your own from scratch.

Cheers,
Sarah
