I am wondering if anyone might have insight into a weird new problem I had today! I was teaching a lab on closed capture modeling (using Huggins p and c) that I have taught many times before -- it is the first lab my students do in Mark, so it serves as our introduction to the software and parameter indexing. I had them work through the indexing using the PIMS, but no matter how they indexed the parameters, when they ran the "current model," it defaulted to the initial PIM structure (p(t)c(t) -- i.e., model MBT in CAPTURE notation). This was happening on 16 different computers simultaneously, so it was not an isolated incident. Even weirder, when we switched over to using the Parameter Index Chart instead, that worked just fine (!) -- unfortunately, it is somewhat less intuitive to first time indexers.

I am really confused -- everything worked flawlessly back in the fall. Maybe there's a new software incompatibility on our lab computers? Or I am missing a new feature where PIMs have to be confirmed before the model is run? I'd be grateful for any advice or suggestions.
