Hi Bill, In the error msg I saw a reference to "openstack". In LC 9 (started in RC-1 I *think*) we no longer lock messages when building a standalone. This was necessary to fix other problems and it is mentioned in the 9.0.0 Release Notes under the section "Breaking Changes".
So I wild guess is that you get that error because when building the standalone one of these stacks receives the "openstack" message, and does things that should not be done while building a standalone. If this is the case, you can add this in the (pre)openstack handlers of your stacks: on openstack if the mode of stack "revStandaloneProgress" > 0 then exit openstack end if .. .. end openstack The same applies to "(pre)opencard", "closeStack". Please let us know if this fixes the problem.
