Thanks for the good description of the problem!

As you are probably aware, Audition writes the audio to temporary files, then when you save, it copies the files to the location you specify.

If you had two drives then I'd wonder whether the temp files were on a fast drive and the saved files on a slow one. But that doesn't seem to apply in this case (and anyway, perhaps it would still be using the temp files anyway...)

I suppose I have to say that running 20 tracks of 32/96 on anything less than a state of the art system is likely to cause playback problems - that's a lot of data all at once to be handled.

But that doesn't explain why it was Ok till you saved.

Are you using any effects and if so have you locked the effects onto the tracks? Can you bounce some of the tracks down, premix them, to reduce the number of tracks needing to be accessed?
