Delete CosmosMotion 2007 study?

How do you delete a study in CosmosMotion 2007? I would liketo clear out a study and re-create it. I know the CosmosWorksallows a study to be deleted, but I cannot find this option in CM2007.

I called my SW VAR, and we did a web meeting. He could not locatethis option either. I noticed if I suppress the parts, and selectthe CM motion button, it will add duplicate instances of the sameparts or sub-assemblies.

Second question: If a study is created without fasteners (shoulderbolts), does 3-D contact need to be manually added to the partlinkages?SolidworksMotion Studies
