Hi Rien Rien > Is there a mean to detect that a tiddler is about to close (in widget's code) ?
No, I'm afraid there is currently no way for a widget to be notified that it is being deleted. In your timer callback, you should be able to check whether the widgets DOM nodes are still in the document, and disable the timer if they are not.
