R-box hangs during playback of last track in a FLAC album

[dunno]

H140; R-box v3.10 and current.
libFlac v1.1.0. 20030126
foobar reports "no embedded" cue sheet.

When playing my only FLAC album (6 tracks),
I can reproduce the following condition at will as follows,

I start track 1 and let it play for a few sec's, then FF to 5 sec's before the end of track 1,
let it play the remaining 5 sec's of track 1 and let it change into track 2,
Play a few sec's of track 2, then FF to 5 sec's before the end of track 2, let it change into track 3,
Play a few sec's of track 3, then FF to 5 seconds before the end of track 3, let it play etc...
( I repeat the above until I'm in the last track),
when it has changed into the last track, FF to 5 sec's before the end of the last track and let it play, when play time reaches 1~0 sec's before the end of the last track, the player hangs in that last track with the disk activity light on continuously, player does not respond to buttons and only a hard reset will fix it.

Anyone else have this issue ?.
