Hi there, I just tried out BeanShell GUI and it seems quite badly broken. AFAICS, this has to do with some reflection magic. Exception during event dispatch: java.lang.reflect.UndeclaredThrowableException at $Proxy3.internalFrameActivated(Unknown Source) at javax.swing.JInternalFrame.fireInternalFrameEvent(JInternalFrame.java:707) at javax.swing.JInternalFrame.setSelected(JInternalFrame.java:1664) at javax.swing.JDesktopPane.setSelectedFrame(JDesktopPane.java:267) at javax.swing.DefaultDesktopManager.activateFrame(DefaultDesktopManager.java:298) at javax.swing.plaf.basic.BasicInternalFrameUI.activateFrame(BasicInternalFrameUI.java:1754) at javax.swing.plaf.basic.BasicInternalFrameUI $BorderListener.mousePressed(BasicInternalFrameUI.java:345) at javax.swing.plaf.basic.BasicInternalFrameUI $GlassPaneDispatcher.mousePressed(BasicInternalFrameUI.java:761) at java.awt.Component.processMouseEvent(Component.java:3812) at java.awt.Component.processEvent(Component.java:3674) at java.awt.Container.processEvent(Container.java:1027) at java.awt.Component.dispatchEventImpl(Component.java:5741) at java.awt.Container.dispatchEventImpl(Container.java:1922) [...] Many of these are thrown and it basically seems to prevent the thing from working at all. /Roman
