More testing: I've found that the position of the standard 3rd person/chase camera behind my ship differs between the old file and the new file. Not that the new DSAce changes everyone's camera; it's more likely that my old camera has been in the wrong place the whole time.
I've got a stack of screenshots for comparison, will upload shortly.
I'm going to clear out my hudshift/jflp.dll files, put on the new DSAce and see what happens.
