Here the solution........
Custom Cursors in Revolution:
1) Open" Photoshop or Gimp".
2) Set mode to "rgb color", "Background Transparent"," width and height to 16 pixels".
3) Change Mode to "Indexed Color", then set to "Exact", "Forced Web", "Trasparency checked" and "Matte to None".
4)Set the view to 400%, then use pencil with color web setted and choose black and white color only!!!!!
Rember color cursors don't work well on revolution........
5)Then Name and save all as PNG....
6) Import in the stack the cursor in the image library .
7)To use your cursor in the script write like this......:
On mouseup
set lockcursor to true
set the cursor to 1100 (Place the number the same of your cursor as you see in your library image)
end mouseup
The cursor will work fine in Mac Os x and Windows xp or Vista...
Personally i have tested my cursors with 2.8 revolution (build 370) in mac os x and in simulation on windows xp (OK!!!!)
Have fun!!!!
