The problem was actually that you have used your nick OSSAgent instead of your email when adding the cursors to the library.
It is now fixed... 😉
Very nice cursors BTW.
Yes, Windows resizes the cursors to 32x32 which is a reasonable size. You can use larger cursors with software like CursorXP, but it is a 3rd party program and may not be 100% compatible in all situations.
