i must have toggled something but the space bar used to play on first click, stop on 2nd click, and rewind to begening on 3rd click. it only starts and stops the playback now, the third click of it does not rewind anymore and is making editing very long. does anyone know how to get this option back?

Hmmm.... If you enable On Stop Rewind to Now in Track View Options, it will rewind when you stop. I don't think  there's a way to make it do what you describe with different behavior on the 2nd and 3rd click.

thank you i ll try that

yea that was it. thankx

Glad that got it. Incidentally, you can get the opposite behavior of whatever option is currently set by using Shift+Spacebar.
