1-I am modeling a product box, so I turn on display background image, I've tried TIFF, JPEG but I got nothing with JPEG and a funny colors with TIFF, PNG working fine for me, the same when using COP.
2-I drew a curve actually many curves in SOP level then tried to pan or zoom, but everything missed up and never came back in the same place.
I'm using 10.0.374, WIN XP 32 and the same for WIN XP 64
cheers
