On the one hand, thanks for the link; I've never so much as looked at Dashboard...haven't got a single widget residing on my deuced Mac(hina), and I ignored that thread other than to take note of the FTM widget's existence.
On the other hand, though, the widget doesn't seem to be of consequence as respects my post, because the obsidianfields.com (Cache) item appears
only when I visit a page on which tacit has posted.
