Well, I did what you said, and now I have another issue. When I try to add a
new item, (NewForm.aspx) I get an error message saying "Invalid Page URL:" I
think there is something missing from after associating the new form  with the
list. (I did do the requisite IIS reset jsut to be sure.) Reverting the
NewForm.aspx and EditForm.aspx back to the site definition also doesn't work.
