PC, Win98 original edition, 128MB Ram, latest Vuescan, it occurs usually after a number, though not a definite number, of scans.
The memory theory is quite attractive for me given that in two weeks or so I'll be getting delivery on a new computer with 1.5GB of RAM. This happens on relatively small (20MB) files but I don't release memory after every scan so I guess that could be an issue. But if it's apt to be a computer problem not a software problem at others are having I guess it's best just to hang in for a couple of weeks. "Thomas B.
