I was the one who had the same probs. If you dl .sea files from
anything other than a Mac it will lose its resource fork (ie a bit
like .info). Therefore mac apps won`t know what it is, even if the
data exists. You need to dl directly to the MAc, (which I do using
MAccim on the SS Mac), or get a util in MAcNEW or go MACFF and search
for utils that transfer these forks across platforms. (There is one
for the PC).
