Just wondering.. Did you exit P6 (and possibly re-boot) then re-load P6 before trying the previous versions? There's no way that P6 (or any other version) should be able to corrupt previously saved files. It's much more likely to be a corruption of the existing version of P6 in memory. Whenever I get an oddity happen in Poser (any version), I immediately quit the program. Sometimes I'll save to a temp file before exiting, depends on how much I've done in the meantime. If the corruptions continue after an exit/re-boot/reload, then it's probably a "re-install P6" scenario... Cheers, Diolma
