I am running a 3c scanner in Win98. It locks the computer up after one scan. I have loaded the latest Deskscan win98 software. In Control panel is an HP icon that says it is set up to Scanjet 6100c. I can't seem to change it to 3c no matter what. I have uninstalled & reinstalled the software. Using an HP SCSI card (Advansys). Tried putting only the scanner on the SCSI chain, same result. It says the code returned from the scanner is C2520A 3503.
