InfoPath filter results truncated from SharePoint list

InfoPath 2007 / SPS 2007

Trying to return a set of records to populate a pull-down control, the list appears to truncate (filter or not) after records beginning AFTER the letter "L".  SharePoint list only contains 182 entries.  No trailing whitespace in text fields.

essentially trying to get a list of projects from a SharePoint list based on an account value specified on the form.  Results are the same for any account selected or apply NO filter.  List appears to truncate at values starting with "M".

xdXDocument:GetDOM("Portfolio List")/dfs:myFields/dfsataFields/dfsortfolio_List/@Project_Name[(../@Account) = (xdXDocument:get-DOM()/my:myFields/my:Account)]

Seen this before?

thanks
