A group of us regularly share a lot of Filemaker databases. All of the sudden, on this one database, one person is able to open it up, but not modify it. She can for all our other databases. I have check the access restrictions, and made sure that even Guest had full access, but she still can't create a new record or modify a field. She is the only one who has it opened too, so it is not shared.
One thing though, is that her computer was recently upgraded to XP, would there be a problem there? I am not sure what to look for.
These are also databases we have been sharing for years, and really no changes the way we do things.. other than she was the only one on Windows 2000, and now upgraded her.
