If you say (define-application-frame foo () () (:pane (make-pane 'interactor-pane :width 400 :height 300))) (clim:run-frame-top-level (clim:make-application-frame 'foo)) You get a window. Hit RET a few times in that window, and the prompt will scroll off the bottom of it, never to return. Is it meant to work that way? -- -Tim
