Hi everyone, I'm attaching a snapshot of a part of my schedule.I've highlighted few summary tasks which are showing "critical" in MSP, but none of its child tasks are critical. When I further checked, I found out that the "start slack" for those tasks is "0" whereas "finish slack" is having value. Usually for all the "non-started" tasks the start slack and finish slack are the same. Because the "start slack" is "0" for those tasks, maybe thats why they are being highlighted as "critical". I still don't know why it should happen like that.
