I find MC17 slower in operation.
For example when I press "next track" button, there a short silence, then again a bit of current track, then the next track.
MC17 is runing almost alone on a machine with 4gb, Windows 7, Intel Core 2 Duo E8400.
I don't know if it is linked with my other problems (regular Crashes or not responding, issues with linked zone)
