I was trying to isolate the problem this morning. We knew that turning off AVG wouldn't allow P10 to function correctly, but who wants to turn off the entire AVG anti-virus? So I turned off the resident shield only. Nothing changed. Then I turned that back on, and turned off the Surf-Shield. Poser10 worked great with Surf-Shield turned off! Then I shut down P10 and turned the Surf-Shield back on, and for some reason started P10 again, and it worked. Now AVG is giving full protection and Poser10 is working perfectly! With AVG at 100% protection, I have restarted P10 4 to 5 times and it works great!!!!

 I guess Poser10 needed to make that first good connection with the internet to establish a working window, and now AVG is allowing conectivity between the two.

AWESOME!
