I am using Access database 2003 and an application created in it. A couple of days ago I noted one strange thing. I can load the database as before, but now I am unable to change it. This looked very familiar, like the file have a read-only format. And Access assure me in it by a message. I looked at Properties and found just empty box near “read-only” text. This feature is not checked. Well, I tried to check it, then uncheck once more, nothing has changed. I am disappointed. Does anyone help?
