A strange thing:

I have a program that allocates a User Port for communication with
Intuition.  I also have a library that allows a user to dynamically
add and subtract Intuition messages desired, using ModifyIDCMP.  My
problem is that if the following happens:

1) ModifyIDCMP(window, MENUPICK)
2) Receive menu selections
3) ModifyIDCMP(window, NULL) -- don't want menu selection messages any more

The thing guru's in ModifyIDCMP().  Is it trying to deallocate my UserPort
and is unable to, or what?  I found no hint in the Intuition manual that
there would be a problem with this.  Oh, it's under 1.1 (Until my Manx
update arrives).  As usual, any help is greatly appreciated.
