XnView: MP 0.97.1 64bits
OS: Windows 64bit
To reproduce:
1. Go to Settings->Formats->Write->AVIF
2. Set Quantization for alpha to Min 16, Max 32
3. Observe AvifAlphaMin=16 and incorrectly AvifAlphaMax=16 being written to xnview.ini
4. Restart XnView
5. Observe the max value not being read correctly (seems to always be 0 or 63)
I also had it happen a few times that all values on the AVIF settings page were 0 after a restart, which may be a rare (unrelated?) UI initialization bug because the dialog under File->Save As->Options still showed the usual values.

I can set the settings to what i want, i always get an image with a few kilobytes. I used a 24 Megapixel image and some smaller images.
