This is due to the very protective nature that Intuition has over its
(not your) IDCMP message port. According to jimm the big "I" *knows*
that all the messages going to that port are in memory that it owns
and has to free, etc. When *you* send a message their you probably
confuse the heck out of it. A more disgusting, but more effective 
hack is to chase down the window, find out where on the screen the
close gadget is, then send a MOUSEEVENT into the input stream that 
is a click on the close gadget. Then Intuition can make up a Close Window
message for you and send it to the IDCMP port. If you this is your own 
program then you can give it your own 'public' port and send messages 
to that. Of course this is what aREXX does for you. Anyone want to come
up with a minimum common command set for a remote control language? 
Maybe another well know port like RCMP (Remote Control Message Port).
We define a common set of 'Messages' that can be sent to these ports
and do the same approximate things (OPEN, CLOSE, READ, WRITE, UP, DOWN,
etc)

These opinions are my own and no one elses. But you knew that, didn't you.
