Inexplicable Audio Import Behavior

I was trying to import one of many audio files into a project (using CB 8 Pro). One file was imported but the last few seconds were missing in the imported data. The import did not require placement that exceeded the length (in time) of the project. The problem file could be imported without incident in other projects - the data really was there in the file. I made an identical copy of the problem file and that copy could be imported without loss. As I said, it was bit for bit identical.

Anyone seen this sort of thing?
