How To Bypass Security Warning on Every Page

Greetings ... and thanks for an awesome site.

I would like to know how to bypass this warning, which interrupts every page on myVRZone that I move to, and every step of adding a new booking to the calendar:

This site contains both secure and nonsecure items.
Do you want to display the nonsecure items?

(button for) YES      (button for) NO      (button for) MORE INFO

I have added myVRZone to my list of trusted sites, but it doesn't help. I am running IE 6.0.29 w/ Srvc Pk 2 on a PC with Windows XP Pro.

Thanks, in advance, for your help with this.

Marta

UPDATE = This problem completely went away when I upgraded to IE7
