The drivers were a few months out of date (the whole machine is less than a year old), and after updating saw a few changes in render performance but the param field thing didn't change.

The deleting/reinstalling thing has prompted me to clean up some things with the installation now I have a better defined work flow and have been having fun exploring some of the features of Poser 2014 I hadn't played with yet, so having fun despite the param field issue... when I get bored playing I'll post a ticket on this and see what comes of it...

Cheers
