Yep... it seems like 60/40 : bad/good for XP Fat32 systems. Also... Re: FAT32 and XP upgrades: Whether Poser is then re-installed can have a further bearing on the matter. Some users have said that their working system has started locking after re-installing Poser, others have reported that re-installing Poser (just 'over the top' of the current installation... nothing is lost) has stopped Folder locks. Whether this is dependant upon the version of XP is unknown. IMPORTANT!!! Also to be remembered is Layingback's discovery... although still to be proved... that the code for loading compressed content in PP and P5 is not succeptable to the bug which locks the folders when uncompressed files are loaded. Hehe... try installing XP on a laptop with 4GB hard-drive. LOL! I'm sure it would run... but will it fit? H:))
