Hi Jan,

I built a standalone including an appleEvent handler, and

* The standalone will only respond to a drop when the file dropped is 
a Rev stack: dropping any other file/folder on the icon just causes 
the Finder to reposition the item dragged.

* If I drop a Rev stack on the icon, that stack is opened, and I get 
NO appleEvents reported by the standalone until I press cmd-Q.

* The $1 parameter is empty.

BTW, I've been dragging my feet about upgrading, and am running Ver 
2.1.2 on OSX.  Might some of my problems go away in a more recent 
release?

If double-clicked, reVise will display a message saying it operates 
in d&d mode only, then quit.

"From [Newfoundland] Dr. [Ed] Mayo's perspective the worst part is an 
ominous shift in demand: ''I do far more vasectomies now than 
deliveries," he says.  ''Far more.''  Whereas he used to receive 
requests to perform male sterilization from men ''over forty with 
four kids,'' since the fishing moratorium he'd started getting 
requests from couples with only two kids...  ''Now I'm getting single 
guys in their thirties wanting a vasectomy.  People don't want to 
have children.  There's this feeling of hopelessness.''"
