The only thing I have heard that can show that schedule is Microsoft Internet Explorer. I know that sucks, but in 7 years of using crewweb I have never heard of anything else working. A few months ago we were complaining about this is the crew room and someone told a story about how they had their brother who does computer work look around crewweb to see if there was a way to get "view schedule" calendar to work in things other than IE. The brother said that even though the calender looks simple it is actually very complex with lots of layers and is hard to render. He didn't really explain why IE is the only thing that seems to be able to render it though.
