I'm running Cool Edit Pro v2.1 and have had problems with it stopping during playback.
It is totally random
I can listen to a recording and it will unexpectedly stop. Press play again and it plays fine, or it may stop in a different place.
Or, plays fine but then stop in any random place during another playback.
This can happen in edit or multitrack view, and like I say is not consistent, just VERY random
