Just an update :)

I was out of town last weekend so I shut my computer completely down. Since firing up Poser for the first time again on Monday, it has been working perfectly all week. No hang ups. No freezing. I haven't changed a thing since the last time it froze up on me (which was after installing SR3 so it wasn't just that it needed upgrading and the SR had just come out anyway).

The weird thing is, I had shut down my desktop completely when this issue started, not just rebooted. So I have no idea what's changed or why it's suddenly working.
