Thanks all,

I have been working with Smith Micro on the issue. My original problem was the loss of the library functions after renders and the only way to get them back was to quit and restart poser. When I discovered the "Content" tab quirk, they seem to think it is related to some system calls and I am trying to generate error logs for them (excellent support!).  I just wondered if any other mac users had seen this. I do have several runtimes and it does take a few moments for the initial library loads. It is just odd that everything works great for a while, then all the ? marks come back and no amount of time will restore things, but it is instantaneous when I toggle the "Content" tab.
