Thanks.
Looks like the same bug infects GetSuperControl, so the wrapper funcion
CtlObj_WhichControl is suspect.  Is it supposed to be calling 
GetControlReference() ? Shouldn't it be the control itself and not
the RefCon value ? 

Anyway -- the good news for all you appearance manager fans out there
is that, except for these couple bugs, auto-embedding of controls 
seems to work properly as far as I can tell. Some of the more complex
emdedding controls need additional resources, so it's a bit trickier
to generate, say a set of tabbed folders dynamically from Python 
if you haven't set up the appropriate 'tab#' resources beforehand. 


BTW: There is a password control with appearance mgr. but I tried
sticking one in a dialog and it doesn't seem to do anything visible
when ModalDialog is called on it. Something is missing -- maybe it
has to request the keyboard focus explicitly. If anyone has a clue
let me know. 

Re: appearance mgr support for dialogs present? 
 Any more thoughts about how to protect function calls if support
 is not there ? For progress-indicator and (I assume) password 
 control, which require a CDEF that's included with appearance
 mgr extension or is included in 8.x, failing to find that resource
 could be the test. 

 Is there an interface to the gestalt calls ?
