I have had the same kind of troubles on a Win95 system with 32 Mb RAM, while nothing bad occured on a Winnt with 128MB RAM or Linux with 128 Mb RAM. So I suspect ram size might be a problem. Since I don't know how MacOs handles ram, I cannot help you any further, but you might try to increase application dedicated memory. On Tuesday 14 November 2000 09:46, Gareth J.
