Don, Thanks for your thoughts. I did try all of the things you suggested – here's the next iteration… It only seems to happen in Overscan mode, always in SceneGenerator, sometimes in Dpaint. The double stripe vertical bar is almost dead center in the screen. Monitor problems seem ruled out because of the pointer/sprite smearing. When I run DPAINT and SceneGenerator I often have more peculiar problems like the pointer/sprite (in DPAINT it seems to be a smeared version of all the "specialized DPAINT pointers with "PICK" and "SIZE" and the arrow all smeared north-south… I have seen NO other symptoms of any kind on my machine over the week since I removed the Insider. The problem didn't occur back when I had the Insider plus the Xetec with 4MB, only since I removed the Insider. If I take the Xetec controller/ram unit off the expansion port SceneGenerator runs FINE on my 512K config… but even if I run NoFastMem with the 4MB Xetec on the bus SceneGenerator and DPAINT overscan have the vertical bar again. Is there ANY linkage between Overscan and the $C00000 memory that the Insider gave me ? I certainly hope I haven't boshed my Agnus, Denise, Paula or 68K but I can't see how a loose or marginal socket fitting on the 68K would give such consistent but limited effects… Is there any diagnostic I can run against Agnus or Denise to see if they are OK ? -thanks – da – via Whap!
