Sounds like your gadgets are changing the screen (as well they should) but
since Intuition now has a lock on the front bitmap (to animate the gadget) 
nothing else in the window can update.  Thus you don't get any of the 
messages you are waiting for after the first time you wait on anything 
else that would update the screen (like printing a new list of lines).  
If these assumptions are correct then what you must do, is to make your
scroll bar something other than a gadget, and animate it yourself (by following
the mouse...)  That way your main task will have the lock neccessary to do
both of the screen updates.   Alternatively, you could violate the lock
(since you know what the user is doing anyway,) and write to the screen 
bitmap directly.  (This could really mess up the screen if you don't call
window to front first, or if a requestor comes up, but hey, if you are
planning on taking over the machine anyway, who cares?

Think?  Who Me?  I hack, sometimes it's more fun to see how many different
ways your code can crash the machine. :-)  (PLEASE don't take that seriously.)
