I tried the compatibility tester, it says there is a problem with file locking, I believe. the main answer for this problem I have received is that I'm running a drive in FAT32 mode (which I am, I have one drive set up for Win98SE dual-boot). However, I'm thinking most likely it's because of having write-behind cache disabled on my temp directory; I did this in order to maintain a stable filesystem that could handle power outages, etc. This would in effect "lock" the file system; it doesn't appreciate things being written too while they are open. This could, I believe, keep Pbooost from properly working while poser was loaded. Which is really a shame, it looked sooooooo cool. I geuss I'll just keep using my bat files to rename directories.
