When I added the JInternalFrame to the applet, I set the "closable" property to true. After reading your message, I checked the

source code, i didnot find "setClosable(true)". So I added code like jInternalFrame1.setClosable(true). It does not work
either. There is no error message.

Then I added some codes to show if it is closable using the isClosable() method. The method returns true. Just con't close it.

Any idea?
