I have 2 Drupal-5 sites (I think it is 5.1x) and I have CCK, Date, TinyMCE, Viewfield and Views on both. Different themes, but nothing weird - standard Drupal themes that have not yet been customized. On one site, when I go "Add Field" to create or edit a content type, I get a dropdown list of existing fields. On the other site, I just get a "create new field" box. Naturally, the second one is where I need a content type that has the same fields 12 times (for a list of wine selections, I need 12 fields for "vintage" etc). The only thing that I know is different is the first site has Organic Groups, but why would that make content type behave differently? I haven't configured TinyMCE yet on the second site, would that matter?
Do I get any brownie points for following up the beer site question with a wine site question? ;-)
