I've been using the trial version of iTunesJoin for a couple of days now. I LOVE that I can join the tracks, yet still access the chapter marks for each individual original track.

I've used the program on several CD's so far. Right now I'm experiencing a slight glitch with one of the audiobooks. It had 4 CD's in all. I joined the tracks for each CD so that there were only 4 tracks.

When I initially click on a joined track, the Chapter mark icon appears in the display bar next to the track information. On all other audiobooks/CD's, the chapter mark icon remains visible and allows you to select which chapter you want to listen to. However, in all 4 joined tracks for this audiobook, the icon appears for about 1 1/2 seconds, then disappears. When the first chapter finishes, the 2nd chapter information shows up in the display, but the chapter mark icon is gone and you can't move between chapters at will.

Any idea why the icon disappears on these 4 joined tracks, but not for the other dozen that I did before?
