Double booking resources in Outlook 2007 and Exchange 2003

We have been running Exchange 2003 with Outlook 2002 (XP) clients since 2005.  Until now we have had little or no problem with double-booking resources.

We recently upgraded the clients to Outlook 2007.  We find that users can now double-book resources if they:
Show the resource calendar by checking the box next to the resource (CR1) under People's Calendars
Hide their own calendar by un-checking Calendar under My Calendars
Right-click on the calendar and pick New Appointment
If the Scheduling tab is clicked, it will show the resource (CR1) listed as the meeting organizer
Because of this, the resource can be double booked.

Settings for the resource's calendar are:
Automatically accept meeting requests and process cancellations, and
Automatically decline conflicting meeting requests.

Permissions are set to:
default - Author
Anonymous - None

Thanks in advance for your help!

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Hide their own calendar by un-checking Calendar under My Calendars

>> Yes should be done only when you are the delegate for the primary calendar.

Reason: This means that on this particular calendar (particularly during that time) we need to create\add a meeeting-request or appointment.

Use the UI, new meeting-request to generate the meeting-requests

Use your (owners) calendar to identify the time and then create new meeting-request and\or generate the correct meeting-requests.

It appears that to be able to schedule meetings, users must be delegates.  As delegates they can directly open the calendar and double-book the room.  It does not seem to be possible to grant permission to schedule a meeting by inviting the resource without also giving users the ability to directly double-book.
