azl. I looked quickly at your file. It opened fine with my machine also. The one thing that bothers me is the size of the window you saved that .pz3 file in. PC's and their video quirks are pretty strange. PC Video cards are tied directly to the OS. And they can do some really wacky things. Open the file on a working machine. Then change the scene window size to 350x350. Then re-save it. And see if it will open on your other machine. It's a long shot. But it can't hurt to try it. ScottA
