I'm having a problem setting vacation/holidays on my project. When I select a resource from my resource pool, and then click the "change working time button" I select the calendar that I want to use. (in this case standard) However, once i click ok to save the change in calendar, it resets itself. If I re-open the same resource calendar, it didn't stay with the selection I just made. Anyone ever have this problem or know how to fix it? Hopfully my description makes sense.
