Haven't noticed this for a while, and don't know if it's new or been around all the time (see below).
Recently started to queue up 8-10 hr playlist before bedtime - like to read to music, then go to sleep to it. At some point in the night, long after I'm in the arms of Morpheus, MJ stops playing in mid-file. Program itself does not freeze. Last nite around the 7.5 hr mark. MP3 file, not corrupted, plays back OK this AM.
Did not think to check CPU or memory utilization before I resumed playback. Other programs (IE 6.0, Outlook Express) functioning OK.
Odd thing, i'll queue up v.long playlists in the office, for playback through Media Server, haven't yet experienced same thing. Seems to be restricted to playback locally.
Anyone else seeing this, maybe someone who's using MJ for a party? (OTOH, after 7.5 hrs. of partying, maybe you'd be too wasted to notice.)
HTH
