Are you running an A1000 with 256K RAM? The symptoms you're describing sound a lot like what happens when code was written under the assumption that the machine would have 512K of chip RAM, and when it tries to use memory that it doesn't have, the screen "freaks out", and the graphics are sometimes sort-of distinguishable, but only because you know what it should look like. This may not be a virus. Try the same software on an A500 or A2000 (but cold-boot the machine, and don't put any other disks in, and power-down afterward ... just in case! Try to avoid testing on a system with a hard drive attached.) - -Spenser - -- S.
