beta4.8.1

Errored initially as no definition file was found. Selected and starts up ok.

Multiple graph views display data.
1st graph window displayed the posaition indicator. Subsequent windows didn't.
However, when scrolling the main window playback position slider, the graph window position indicator bars appeared & move all together when scrolling the position.

Knock timestamp works.

Playback:
cpu usage 22% on slow. 26% approx when running fast.(same as beta4_8).
Position indicator now counts about twice as quick on fast as opposed to slow.

Excellent!
