Group alert message

[Marmaduke Running]

Working in Indesign in CS5 I resently getting this  error message

"Group Alert

a group cannot include both locked and unlocked objects"

when I try to group objects that are on on the background that is locked. All objects are on the same layer.

How can I get the grouping command to ignore the locked items.?

You are in very unsupported territory. You can try running it under Windows 7 compatibility mode but beyond you are completely on your own.
