mde file settings being changed?? How and Who?

[moleboy]

Hi,

The mde file opens by loading a form, which is the main menu screen. This also triggers a few queries. Just recently users are reporting that when they open the mde file they get the database view. So either Access is failing or someones hacking.
Can anyone shed some light on how a user could change this setting on a mde file and how I can find out who's doing it??

Thanks
