Locking the Product List in ACT 2009 Premium?

[neonz]

In ACT 2005 it was easy to block Standard Users from updating the Product List on their remote databases.  We've recently upgraded to ACT 2009 Premium ST (Version 11.0.0.367) and I can't seem to locate where this setting is.  We do not want users to edit, add, or delete items in the Product List.  Any ideas?  Field level Security?

The Product Type is different than the Product List.  Even with this suggestion, Standard users still have the ability to Manage the Product List.  When users  create an Opportunity Line and select an item from the Product List, they also have an "EDIT LIST VALUES" option at the bottom of this list.  That's what I need removed.

Your right, sorry. But as for the original question no, I do not believe it can be locked.
