>>I've been having a problem with data base corruption when I build referential integrity into it using the data environment. Anyone else having this issue? It doesn't matter if I access the dbc on my laptop or another drive. I selected one table which had a relationship and selected "referential integrity", then seleced "cascade" for deletes and saved, and immediately got the .dbc corruption message....

I'll give that a try. I thought it might have had to do with my resource file, so I deleted it and tried again. It still corrupted. I also validated the database, packed the dbc and still got the same results. I'll give your suggestion a shot.
