Quote - EZMat always attempts to update the Preview for you anyway, so you should not need to do this.. This may not work, depending on your version of Poser. The function has a history of being buggy.

Ok I will stop my attempts then. I use PoserPro 2014, build 10.0.3.26510; to my knowlege the latest version, on Windows 8.

Quote - However, I'd like to rule out any error messages. How are you trying to call this method? And what is the error message?

I cannot remember exactly. I took the code out when I noted the other plugins did not update the screen either. It was not very informative, just saying something like. 'Oops this plugin did not work correctly'. I noted it was associated with me just calling the method, without the 'Poser.' prefix. When I added the prefix, it did not appear.
