There is a bug in this module ! It forgot to set the ES register (it used
another register for setting the pointer to the cursor mask). In addition,
the definition for the cursor and screen masks are WRONG. (I just
use an FAR array of 16-bit integers). They don't set the cursor shape
in their tests, right ?

I fixed it, because I use this library in my programs (for private
use like you, so far). If you need these fixes, please e-mail and I will
send it to you. (I am at work right now and have the sources at home).
I got my information for setting the mouse cursor from the manual which
came with the (Genius) mouse.
Perhaps you could look at your mouse manual and fix the bug yourself
in the meantime. As I said it's just that they don't set the ES register
before they call the mouse driver.
