You did used to have to perform some magic tricks on cursor images 
before they would work. They were pretty hard to create. They had to 
have a color palette of exactly 3 colors only, and the colors had to be 
in a specific order. After importing the image, you had to paint on it 
briefly (you could click with the pencil and then undo) in order to 
convert it to something the engine understood; RLE probably.

A couple of versions ago, that was fixed and we can use any normal image 
now. That's nice because the cursor restrictions had been around since 
the beginning of MetaCard.

You can set that. See "hotspot" in the dictionary.
