Hi!
A problem that arises with running the iPad version of ASP, is the system cursor terror. For a temporary solution I found a program named Mousecape that enables you to create your own cursor. I made a 4x4px cursor with red in the middle and a black border, exported it as png and added it to all sizes in mousecape. Then I applied the cursor and it works well when painting and is visible on both dark and white backgrounds. If you can't find it just shake the mouse as usual.
