I made this drawing last week and it was fine. Now my 2nd page does not show anything and the entity tree has all the constituent parts grayed out. I also have the assembly model open and I can see all the parts. All parts have been set to resolved and I have clicked rebuild multiple times. I click on the other page tabs and they display just fine but, when I click on the page 2 tab it teases me with a glimpse of what I arranged last week before blanking the image out.

I feel like I am missing something stupidly simple and I would love any input you folks might be able to offer.

Thanks

Jonathan
