Clipping on moving file from XP to 7

[miqna]

I have a colleague running Audacity 1.3.11 on a computer with XP. She used to send me files which would open on my computer with Vista, no problem.

I recently upgraded to a new computer with Win 7 64 bit. Audacity workd fine for me locally, but when I open a project file from my colleague, the audio has massive clipping (red peak lines).

I have tried running Audacity in XP(sp3) and Vista(sp2) compatibility modes with zero joy.

Then, I upgraded locally to 1.3.12. Again, no joy.

Has anyone had this problem, or is the dev team aware of it????

Thanks.

Some more details to add...

We have the exact same installation, just different OS. Same microphone for recording.

I have older Audacity projects which were created by me on the old Vista machine, and they open just fine - they do not have the same problem as data files I get from her.

I've even had her save the files on CD, then open them from the CD and she sees everything is fine. I open the SAME CD, and get the excessive volume on the tracks...

The vertical red clipping indicators can sometimes look worse than they really are. The audio does not need to clip by much to produce a lot of red lines.

Is it a multi-track project or just a single audio track?
What does it sound like if you play it?
