I just put in smp3 in my status bar and noticed that it always shows 00:00, no matter what I have selected. At one point it showed something like "49710 d 6:46" but when de-selecting and selecting the same file it showed zero again.
Two caveats:
I see the "audio tag" viewer plugin doesn't list mp3 as a supported type
I have dBPowerAmp installed which has its own shell extension for viewing audio file tags
Could any of the above two relate to my issue? If not, what could be the problem here?
