The ability of the browser to block exiting from the page is based on handling the 'onbeforeunload' event trigger. However, this event is not supported by all browsers (and also apparently not by HTA files either). Fortunately, there *is* a fallback event trigger that all browsers support: 'onunload'. Unfortunately, this event only permits you to add some 'cleanup' handling on the way out... once the 'onunload' trigger has occurred, you cannot cancel the exit action entirely and remain on the page. In order to provide *some* kind of 'data safety' for browser's that don't support 'onbeforeunload', you can use this plugin: http://www.TiddlyTools.com/#ConfirmExitPlugin Although this plugin cannot stop the document from being closed, enabling the "save-before-exiting" setting will give you the option to *save* your changes before continuing to exit, so at least your work won't be lost. enjoy, -e Eric Shulman TiddlyTools / ELS Design Studios --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
