perhaps this is a version problem but my scribble window does not do  
anything:

in listener:

Welcome to Clozure Common Lisp Version 1.3-r11936  (DarwinPPC32)!

;Compiler warnings :
;   In LABEL inside an anonymous lambda form: Unused lexical variable V
;Compiler warnings :
;   In (VIEW-DRAW-CONTENTS (SCRIBBLE-VIEW)) inside an anonymous lambda  
form: Unused lexical variable RECT
; Warning: previously declared methods on #1="acceptsFirstResponder"  
all had the same type signature, but #<OBJC-METHOD-INFO -[ScribbleView  
#1#] #x897DE96> introduces ambiguity
; While executing: CCL::%DECLARE-OBJC-METHOD, in process Listener(6).


then when clicking in AltConsole:

 > Error: #<PARSE-UNKNOWN-TYPE unknown type (@METACLASS ScribbleView)>
 > While executing: CCL::CHECK-NS-EXCEPTION, in process Initial(0).
 > Error: #<PARSE-UNKNOWN-TYPE unknown type (@METACLASS ScribbleView)>

 > Error: #<PARSE-UNKNOWN-TYPE unknown type (@METACLASS ScribbleView)>
 > While executing: CCL::CHECK-NS-EXCEPTION, in process Initial(0).

etc.
