Re: files move when changing project tempo

As Rob suggested, the reason is that audio clips have their start times referenced to Musical M:B:T time by default. This is appropriate if the audio is recorded to a click in the first place, and you want clips to retain their positions relative to the M:B:T timeline when changing tempo (with Autostretch enabled on audio clips as well). Changing clip Timebase to Absolute for all clips will allow the clip start times to retain there absolute timing.
But if you're not recording to SONAR's click, I don't know why you would care what the project tempo is...?
As for audio clip lengths changing when you change tempo, that's because the M:B:T timeline is the fixed visual reference in SONAR. Rather than having measure/beat lines get closer together at a higher tempo, for example, the Now time cursor travels faster. This means that an audio clip with a fixed absolute length will get longer, visually, to have the same absolute run time as the Now time cursor traverses it more quickly.
This is a little unintuitive if you're used to working in other contexts/programs where absolute time is the fixed visual reference. I'm not sure how many DAWs - if any - are built this way.
