It is very important for application like this not to crash during live performance. So I had three crashes within 6 hours while draging&droping files into Prepare tab. Now I use rekordbox 2.1.1 powered by MIXVIBES without any crashes while playing and dropping files into playlist. MBP 6,2 OSX 10.6.8
