Attached is a patch which fixes mantis bug 2645 where scripts in child prims freeze after being unlinked from the root prim. This got introduced some time after the 0.6 freeze. Have checked test suites pass even after nant clean ;-) http://opensimulator.org/mantis/bug_update_page.php?bug_id=2645 Also removes a redundant ResetIDs call Regards, Chris
