Presentation Actions with Active Lisp Listener

	Environment: Symbolics CLIM early release 1.0.

	I created a CLIM frame with a Lisp Listener :interactor
	pane, where I evaluate a form which runs until I type the
	character "q".  Mouse sensitive output is drawn on several
	frame panes while the form is running.  I defined presentation
	actions to "pop-up" a window, when the mouse is clicked over
	the mouse sensitive output.  Only one minor problem -- while
	the form is active, the mouse handling appears to be inhibited.
	After I type the "q" and the form returns and the :interactor is
	waiting for input, the presentation actions work just fine.

	Is there a way to have the presentation actions enabled during the
	the running of the :interactor pane form?  Do I have to create two
	CLIM frames and have the :interactor running in one, and the mouse
	sensitive output drawn on the second frame where the presentation 
	actions will be defined?

    Have a background process that is waiting for input on the same stream
    as the interactor.  Be very careful, use locks.

Using background processes and locks isn't portable, is it?  I should have 
specified that I am looking for a portable CLIM solution.

	Thanks for any suggestions.
