I have recently downloaded Athena and was sending a project file to a colleague who uses an older version. When I sent it, I checked 'Backwards compatible project file', then saved the project and closed Athena, then sent the file.

I had selected some normalization parameters as follows:

When he opened the file, most of the parameters were the same, except the window type (changed from 'Hanning' to 'kaiser-bessel'). Is there any reason for this? Any way to maintain the window function between versions?

Thank you,
