I have the same problem with the neg holder supplied with the 8200Ai: Align the negative within the gate of the holder, close the top hinged section and the negative jumps enough to require a second or third attempt until I lose all he will to sort it out and put up with the misalignment. Really frustrating, but even more so with half frame negatives due to the slightly larger negative than the gate of the negative holder. (With regard to half frame issues, I have considered obtaining a spare negative holder and removing the inter-frame plastic sections, but having thought further about this I suspect it could lead to issues holding the negative flat.)
