I would like to see the contents of one of my windows scroll continouously
as I slide a prop gadget up and down, rather than just get one change
when I finish let go of the select button.  Preferences and Manx's SDB
give this "instant feedback", and it's nice.  I thought of two ways to
accomplish this, and neither seems to work.  One way is to set the
prop-gadget's FOLLOWMOUSE flag and check the gadget's PropInfo structure
every time I get a MOUSEMOVE message; the other way is to check the
PropInfo each time I get an INTUITUCKS message.  The problem is that, as
soon as I press the mouse's select button, all MOUSEMOVE and INTUITICKS
messages appear to be suspended until I release the button (at which
point I get a flood of MOUSEMOVE messages).  I have tried various
combinations of GADGIMMEDIATE, RELVERIFY, and FOLLOWMOUSE in the
gadget's Activation field, and I reply to all messages.  Am I missing
something?  If I ever do succeed in getting continuous messages, is it
reasonable to expect the PropInfo structure to be updated continuously? 
Is there another way to get the desired effect?

Thanks,
