The changecount is changed by the core, if you edit / save a tiddler. In the backstage there is an option: "Don't update modifier username and date when editing tiddlers" which tells TW to not modify the tiddler, if you just enter edit mode and hit done without actually changing stuff. So you should check this setting and see, what happens.
This may prevent the save mechanims, to edit tiddlers, that you actually don't. .... I'm not sure, if TiddlerTweaker respects, this setting. ... -m -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
