[AccessD] Access 2003 to SQL question (cross posted to accessd and sqlserver lists)

I have an app that has an Access 2003 front end and an SQL 2005 back end.
Everything has been going fine, but now I noticed that I cannot update one
of my tables through the FE.  I am able to update through the Management
Studio, but need to be able to do it through the FE.  It seems to me that I
had this problem before, but I cannot remember how I fixed it.

Any suggestions?
TIA
