Group Adjustment Not Working?

Just recently my Aperture has stopped allowing me to "Group Adjust" images.

For example:

1. If I select a group of images and want to rate them with a star ONLY the primary selected image* is rated and NOT the entire group which is selected.

2. Lift and Stamp tool. If I adjust an image and Lift the settings to be stamped on a group of selected images and press the Stamp Button at the buttom of the Aperture Window the adjustments are only stamped on the primary selected image. However in the Lift & Stamp HUD if I press the Stamp Selected Images the adjustments WILL be applied to all selected images.

FYI = primary selected image refers to when an image has a BOLD select line around the image while the other images in the selected group have a thin line denoting they are selected as well.

Is there a way to correct this problem?

I've done the Repair Permissions and the Repair Database.

AND.... NO the Preview mode is NOT on.

Thanks in advance for your help!

Cheers,

Spencer
