Incidental copying like that has never been tested in court, and neither have EULAs for that matter (I'd bet my ass they're invalid). Everything gets buffered somewhere, even in analog processes, even in physical processes. Stop making infringing copies of my work in your brain! Even if it was deemed within the purview of copyright, it's squarely within the realm of fair use -- they aren't violating copyright any more than a corporate mailroom that scans and duplicates incoming correspondence. They took it in in good faith, they aren't publishing it outside their own organization, and they aren't making copies to get more 'use' out of it, so it doesn't matter.
