A friend just got his rev 4.2 2000 yesterday and first tests indicate 
something's wrong with the machine. In the Workbench, attempting
to drag icons (or sometimes even just activating them) fails in the
following fashion: 

Within 20 pixels of motion, the icon drops back to the Workbench (without
text) and further attempts to move it or activate any other icon fail. The
pointer continues to function until one attempts to activate an intuition 
gadget (drag bar, right mouse button anywhere on the screen, etc). Here
the pointer hangs (but you can still A-M/A-N) until a disk is inserted
in any drive. Input events are stored while the pointer is hung and 
processed properly following the disk insertion.

It's a vanilla 2000 with an external drive. And *any* workbench disk
will do.

Seems like someone (Intuition?) is leaving the layers locked; hence the 
pointer position is updated until an event requiring drawing on the locked
layer occurs. It seems to miss a BLITTER_FINISHED signal during the drag,
so it never thinks the drag is done so it never thinks to unlocklayer().

Please send any comments to me (ali@rocky.stanford.edu), or, better yet,
if you can get it to work, to my friend Art (r.racer@lear.stanford.edu).
