Gary and Ken have both reported this error (although I'm not sure yet when that occurs:
{"notices":[{"type":"cri","text":"Query Error: Table 'gary_jamroom.jr_ujgooglemaps_item_key' doesn't exist"}]}
Does this change mean that only modules using a datatore and having items to embed can use the tinymce popup? IpsumJam and GoogleMaps don't have any actual items of their own, yet they use the popup.
