[Waystone]

Nope.. same problem, and the solution isn't working for me. I click the X, enter the desired start date, and the constraint reappears. Click X again... repeat ad nauseum. ;)

It seems a tiny thing to be really bugged by, I know, but it's brought my use of the software to a grinding halt. I can't keep going till I have the capability to backdate.

There are no people or resources attached that might be exerting other constraints, no priority, and no dependencies.

Help... :)
