I was working on a file that I hadn't worked with in quite a while. After rendering it, I went to change something and got the first "resizing window" error msg. So I closed it, opened Poser. Same thing. So I set the Preferences to Factory State. Same thing. So I restarted the computer. No effect. Same thing. The window size for the PZ3 I was working on was pretty standard - 640x480 or so. Nothing drastic. The OBJ-in-a-different-folder might be a reason. But it remains in this state even when I try to open a new scene or an existing one. It's all very odd. I have too much to just nuke Poser and reinstall.
