I currently have version 3.1 installed on Mac OS X 10.7.3. There are instances were my compressed far files will give me an error with far file number 17. It only happens with file number 17 for some reason. When I try to uncompress with Keka for example, I get no error and the files in question decompress correctly. Like I said, this is happening on multiple occasions, and the error is always with file number 17.
