Quote - FWIW...I have Poser on two computers.  On both, I allowed the Flash update but not the IE update. Updated both computers, and Poser works fine on both.

Thanks, that does seem to point the finger at IE11.

I was just talking to the IT guys here at work, curious because IE11 hadn't shown up in my Patch Tuesday updates. They've blocked it for now because it doesn't play nicely with some of our systems, including the one we use for booking holidays. Plainly that needs as close to 100% uptime as we can manage. :)
