Hi - I've looked at this too long and I haven't figured it out as yet. I can't figure out why I can't change the task constraint on a task that is not yet started, in a plan that is approved/active. When you edit task, the task constraint is grayed out. I can't change it here (see below) or anywhere. I'm a sysadmin, so permissions shouldn't be a problem. I'm sure the answer is obvious, well, to some, not to me. Anyone have ideas? Thanks, Eric Lucas Eric MPM eric.lucas@crowley.com Crowley Information Technology
