  I'm trying to write a mouse handler (I know there are others, but I 
want to do it) and I seem to have a problem - everytime my handler is 
called, the relevant bits in ax are all 1.  I'm using a real-mode 
callback to get to my handler so I'm wondering if that callback is 
fiddling with ax.  ax is a parameter for the mouse handler so if the 
callback is messing with it, it's got to quit doing that.  So, is it the 
callback or do I have some other problem?
