I was really hoping someone would have suggestions with this issue. I posted yesterday and no answers. I love Blender’s interface and it’s so sad for me not to be able to use it with confidence. I don’t want to hurt my video card. I have plenty of VRam: 512 megs and have the Radeon 4850 video card which is a good card for my Intel 24" I Mac. I see no slowing at all when I work with Blender. It’s only when I quit the app I saw a white horizontal line running all the way across the lower portion of my monitor and as I said previously, when I rebooted the line was gone. This doesn’t happen using any other application, so I know it’s related to Blender.
Isn’t there anyone out there that can help me with this? I won’t use the app again unless I get some advice. Please help! and asap because I was working on something for a video and hate to loose it. I even bought a book from the e-store to study too.
