No but I have a similar experience: We had an outside service bureau can in some images, slip them into different formats (TIFF, EPS, JPG) and put them on a CD. The JPG files were unreadable. After seeking the Autoboot virus (luckily unsuccessfully :-) and through tests, they found that making the CD on the workstation - the JPEG files were OK, but that when they copied them to another station, over an EtherNet network, the JPEGs became corrupted. Very strange. They do have a mix of Macs, Unix and NTboxes on the network, but don't know why only JPEG files were affected. Perhaps you re having a similar, mysterious, problem. jonathan ------------------------------------------------------------- !
