iMac 400DV. I've narrowed out memory problems already-I've got 190+ and have virtual memory on as well. Using Mac OS 9.0.4, which is the same as I've used as long as I've had the camera. Program is called Kensington CamWorks & has worked fine up until the last couple weeks. The image shows on the computer sreen fine, but when I save it to the HD, it appears as vertical lines. What I find most troubling is that I don't recall doing anything that would cause this to happen. The ONLY thing that I've done which that might POSSIBLY be interfering is downloading Windows Media Player....& if that is causing trouble, I don't know why.
