This forum is for reporting bugs in MediaMonkey for Windows 4. Note that version 4 is no longer actively maintained as it has been replaced by version 5.
Seeing as the screenshot is showing the Non-Skinned version with the WMA Lossless codec selected, I figured this might have been a by-product of that other bug. However here, in the skinned version, selecting WMA Lossless with those settings shows -1 kbps. Though... what's it supposed to show? (Sorry, not a WMA Lossless user... or WMA user for that matter)
