and it deletes...then comes back?

Only if you push Undo.

Unless it's a haunted gadget.

"haunted gadget", is that an official term? :)

Nope, I swear. And if you move a gadget, then close the page, it's back to its old spot.

I was showing someone at work how to add gadgets to a default iGoogle page where he wasn't signed into a Google account and we had some weird behavior where the gadget would be added, then we changed a value in settings of that gadget and poof it would disappear. Switching to a different tab in iGoogle and back would make the gadget reappear but the setting was back to the default setting. I've never seen that before. It was on IE 6.0.2. Win XP.
