I just discovered that arangement settings of a folder made under PM 4.6.1 beta 7 OSX are not the same (or maybe not working at all) under PM 4.6.1 beta 7 Win XP. Is it possible that arangement settings aren't working the same way under the two different OS or is it a bug?
I would not be surprised at all that an arrangement made on Mac OS X wouldn't work on Windows and vice-versa. They're two different implementations.
