I'll take a look. > and there are plenty of getAudioPreviewData calls (and > friends) even though surely it should know no preview has changed. I don't understand what's the big fuss about this. getAudioPreviewData() is normally called during a redraw as soon as a new part of an audio segment has to be drawn. It doesn't recompute the whole audio preview, it merely returns a pointer to the preview data cache, out of which the rectangles are computed. -- Guillaume. http://www.telegraph-road.org ------------------------------------------------------- SF.Net email is sponsored by: Tame your development challenges with Apache's Geronimo App Server.
