Hi Erika, 1 - We sent the video link to our Project Owners and we recommend using our Standard with Task Constraint view (which is just the standard with with the Task Constraint column added and then we made it available system-wide for our users). That way when they make a change to one task, they can see that the next task changed and they can easily click into that column and fix it back. 2 - The reason I said this messes up the recalculating is because instead of moving the days of the next task, it keeps the dates of that task the same. The Must Start On prevents the next task from moving where it supposed to. (example: you move Task 1 a month, Task 2 - instead of moving a month as well, will just change to Must Start On and the originally dates will stay. That is not expected behavior. So it isn't that Recalculate Timeline doesn't work, it is just that the task constraint prevents the days from adjusting correctly. 3 - Fixed Dates are fixed. So they don't recalculate as they aren't supposed to move since they are fixed. :) Anthony Imgrund FCB
