XnView: MP 0.98.4 - 64 bit
OS: Windows 64bit
unmarked "Audio/Preview" doesnt stay "unmarked" after restart program
Effect: Can't messure any... just strange...
To reproduce:
1. go to Settings/Browser/File list/Custom filter/Audio/Preview
2. unmark it and close program
3. go to Settings/Browser/File list/Custom filter/Audio/Preview
4. it is marked again.
Actual behaviour (bug): stays allways ON

Expected behaviour: should show preview off for audio-files
