Hi Woland99,
If you're getting different results depending on which program you're dragging these WAV files into, then I suspect that the program is doing something to the files. When you drag a track name to the Drop station, a WAV file is generated, and the exact same WAV file is dragged out of the Drop station, regardless of which program you're dragging into.
Next, please try this:
Drag a WAV file to Explorer, then try dragging that same WAV file into both Reaper and Traktion, let's see if they give you different results.
Drag and drop is working flawlessly for me so far, so we'll have to do these tests on your machine. You're welcome to call our tech support line if you'd rather discuss this over the phone though. 1-866-983-2474
Thanks
