zcurses scrolling

[Ray Andrews <rayandrews@eastlink.ca>]

All:

I'm experimenting with mouse input and getting strange results with the 
scrolling wheel. If I grab input like this:

     zcurses input status key keypad

... then the scroll wheel returns either 'UP' or 'DOWN' in '$keypad'. So 
it simulates the arrow keys, which is logical and it works fine. 
However, when I attempt to handle mouse events explicitly:

     zcurses input status key keypad mouse

... things change.  Now, if I scroll up:

     $keypad is 'MOUSE' and
     $mouse is  '0 40 18 0 PRESSED4'

... but if I scroll down:

     $keypad is 'MOUSE' and
     $mouse is  [unset]

So if I want to capture mouse clicks (which is working fine) then I'm 
not able to capture scrolling down, tho I can capture scrolling up.
