Wavepad and Wave Repair

[Joseph]

I recently downloaded a program called Wave Repair for the purpose of detecting peak clipping in my wave files. Since then I have had unusual results making volume adjustments to wave files using wavepad. Some files don't seem to respond at all to volume adjustment while others respond too much. I am starting to get a sneaking suspicion that some adjustments I'm making to one file are actually being registered in another file. The other day I modified a couple wave files and when I played them back one file had the other song in it!!! Has anyone ever heard of this before?
