- what format are the tracks?
mp3 and flac.
- does crossfade work when changing tracks of the same format?
The crossfade is "partially" functioning, I couldn't notice before because it's so fast, probably 100ms or so, but it's not honoring the settings that I check (for example, 3 seconds), and even if I disable completely in the settings, it's still doing the fast crossfade anyway.
- are you using the Store installation or the Installer or Portable?
Installer 3.3.7310
- what is the full path to MusicBee.exe?
C:\Program Files (x86)\MusicBee\MusicBee.exe
- and where are your music tracks stored?
Internal and usb hard drives, it doesn't work with both.
- is there anything in the error log around the time the tracks switch (help > support > view error log)
No, it's empty.
I seriously doubt it's your security software, but just for the hell of it, try white-listing the entire MB directory in your AV software.
Just disabled it completed, tested again, to no avail.
