[CM] new-effects.scm problem in snd

[Bill Schottstaedt]

 > Unbound variable: current-screen

current-screen is defined in snd-motif.scm:

(define (current-screen)
   "(current-screen) returns the current X screen number of the current display"
   (DefaultScreenOfDisplay
     (XtDisplay (cadr (main-widgets)))))


You could load snd-motif.scm, or add this function to
new-effects.scm -- I'll add a check for this problem
to new-effects.scm.  Thanks for the bug report!
