I use 'normal' in SONAR also, but that really only saves the edits and settings. The choice 'bundle' for save is supposed to save everything, including source audio files, so you can take the entire project to another computer. I'm guessing that, if it doesn't work for you, it has something to do with the way BIAB creates a temp folder with your audio files before they then go into SONAR. As you know, in SONAR the editing is non-destructive, so the original audio files have to be stored somewhere. This process also accounts for the delay you see before the audio file loads into SONAR.

I researched all this during beta testing. I'll take another look at where these files are going and how it works internally.

As an aside, apparently there are different ways to accomplish drag and drop in different sequencer programs. For example, it reportedly does not work directly in Cubase and requires a workaround.
