I have noticed this issue on several occasions. Working away in Poser Pro 2012 for a while and starting and stopping test renders or site image renders and Poser will go through the pre pass just fine then go through part of the final render and stop with the same popup you see when a render is complete but I only see something like the image you see here.

Having to resort to close Poser and start it again to do a render and hope like crazy it finishes. This has happened on many occasions but I just never go around to reporting it until now.

Steve I know you are reading this. Please have the guys look into this one soon as it is a time waster fopr me. I hate to waste time. Grrrrrrr.

By the way that is my friendly Grrrrrr. :-)

Then you will get my angry Grrrrrr. :-)
