It isn't so much that something can wrong, it's more about the strain on 
the CPU. Since you are using a mousemove message to check the button 
position, it isn't as bad as when a script does the same thing inside a 
repeat loop (which is almost always a no-no.) I think your method is 
okay, but there would be less lockup on the CPU with Klaus' method.

For those who haven't seen it yet, there's an explanation here:
