Currently, to close the About box in the Desktop Application projects, the supplied source within the closeAboutBox() method merely hides the dialog. Each time the About menu item is clicked a new dialog is created. Would "dispose();", therefore, be a more appropriate close operation for the About dialog rather than "setVisible (false);"?
Yes, you are right. I will modify the template to contain dispose() instead of setVisible(false).
Fixed - I have modified the templates. Modified files: http://hg.netbeans.org/main?cmd=changeset;node=a6f16c1e772e
