Then I remembered that the drive had become full up when I tried to render the mix. So I quit T2 and it asked me if I wanted to save the changes before exit, alas I said yes!
Anyhow, Tracktion obviously tried to save but there was not enough room, but neglected to tell me, so I lost the whole song
If a warning dialogue box could popup when there is not enough room it would certainly help on these rare occasions.
N.B. T2 also dosen't inform when rendering a song if the destination drive is full, it simply cuts the wav file short.
