Well I don't have any other addons, just python scripts and everything has worked fine up until now when I had the problem with EZMat and then tried everything I had installed just to make sure.   As I said I only just discovered the problem with WW too because I had been using the stand-alone version I had bought before it became integrated into Poser. 

Do I uninstall PP2012 and make a clean install and then SR 3.2?  I haven't installed much in the PP2012 runtime since I have linked all my other runtimes so I can probably do it without much hassle.
