In my game the wait cursor is invisible. So during blocking commands the player can't see it. But he can still move the mouse around and if it's over a GUI button then the mouseover-image is displayed.
I would want that the wait cursor doesn't trigger the mouseover-images.
Sounds sensible - thanks for the suggestion, I'll add it to my list.
I'm all for. In MI1.5 I had to do a custom Wait1 function to work around it.
