I haven't checked properly, but I can take a guess at this... The file read primitive in FilePlugin tries to read from stdin 1 character at a time (presumably to get around the line buffering that is done, but I haven't gone through the history. At one time I think it modified the terminal settings, but that code is #if'd out). For all other streams it attempts to read the requested number of characters. StandardFileStream>>readInto:startingAt:count: assumes that primitiveFileRead will always attempt to read count bytes, but it actually only attempts to read 1. Cheers, Alistair
