Thanks, Sarah; I read the "About porting" thing carefully... or so I 
thought, but it mentions the HCaddressing property on the very last 
line.

I had browsed the hyperactivesw.com site also, but it's hard to search.

Anybody have any further advice about the problem with buttons and the 
Inspector (re-described below)? If not, I'll consider it a bug and file 
a report.

Clearing HCaddressing had a strange effect on another behavior. With
hcaddressing true, the "Size & Position" view of the Inspector was
grayed out when inspecting buttons. Changing the view to something else
(e.g. Basic Properties) and then returning the Size & Position enabled
the controls, but then clicking on any of them re-disabled them.
Clearing the hacaddressing property removed this behavior, and the
controls are now always active. What's the rationale there?
