Okay, now the non-working days are grayed out. I think I exited PL and reopened it. Don’t understand why. Now, however, if I make changes to the calendar, I have to exit PL and restart itto have the new calendar incorporated. Previously I could just Save the current version, with the new calendar then Open that file – over the current copy when promped by a pop-up box – and the changes would be incorporated.
Who knows whats going on. Seems it should happen automatically or there should be a refresh option that would recalculate my schedule with the new calendar.
