Ok, build 83 has shown even worse problems.
It's not popping up a "Save changes" window at all. However it is changing tags all over the place. Any file on the "Recently Ripped" playlist is getting changed. An example, I was ripping more CDs today, one of which was an old Good Charlotte CD. Then after ripping that CD I ripped two CDs from a local band. I then went on to rip about 6 more CDs. After doing all of this, I decided to look at the "Recently Ripped" playlist when it popped up. Here are the changes that took place without my prompting.
3 CDs were changed to the Artist Good Charlotte
The titles of those 3 CDs, plus one more, were changed to the title of one of the CDs from the local band.
The date keeps getting changed, on all files in the playlist, to whatever the date was on the last ripped CD.
This is considerable more problematic than the window popping up. I really wish I knew how to duplicate the problem for you guys, but it seems to be totally random.
If you need the Debug Log or anything else, just let me know.
