Richard,
I am going through your Microsoft Access Tutorial 103.  My database has been developing very nicely and all was well until I added a command button in a form.  I implemented the close command on the form and then saved my database.  Now when I open my database, I receive a message that says my database contains macros and I have to choose to disable, or enable the macros before opening the database.  This message is driving me nuts!  If I choose to disable the macros the database won't open, so I have to choose to enable macros, which then says they can contain viruses.  
Why did this happen? And how can I get rid of this message.
Thank you,
Angel
