I can confirm that the problem with the Advanced Preferences is with the non-american keyboard. I have a french canadian keyboard and it only works if, in system preferences, I change the input language to American. Also, I found out that the"Per torrent limit" setting is not working properly. If I put 100, the torrent always max out at 75 connections. If I put 134, then I max out at 99, which is also about 75% of the number I entered. Strange... Maybe it's my other settings?
