They didn't say not to mention it. I wrote to the tech support address and I got this link in reply. I was told it was a "common known issue" wih Poser. It seemed like a stock response... personally typed but not specific to my case or computer specs. The phrasing led me to believe this is a fix for peole with high virtual memory allocations, which Poser does not agree with. In my case, Poser was not able to display 3D objects at all. I could only get a grey outline when I hoveered the mouse over the object, and trying to render crashed Poser without an error. As it turns out it was due to a 512 Mb memory upgrade I installed last week. Again, odd. Hope I haven't committed some evil releasing the link, but I don't assume things sent to me by techies are in confidence. Phoenix
