I'm running PBooost under Win2K and at first everything was fine; I could even switch banks while Poser 4 was running, for a few tries. Then for some reason, it wouldn't do that; I had to exit Poser whenever I wanted to switch banks; inconvenient, but workable. Over the last few days, however, PBoost won't switch banks at all, not even when Poser is not running at all. I got CorrectReference and have been trying it out, but the problem still has not been fixed. I've spent a lot of time sorting out files into different banks, and it'd be a major inconvenience to go back to using Poser without PBooost. Has anybody else encountered this problem and solved it, or developed a workaround? I notice that somebody mentioned in an earlier thread that some configurations of Win2K do work correctly with PBooost; anybody know which ones do so? Thanks, Guy Hoyle
