Last Codec Selected Not Retained Consistently

[eugbro]

I rip CD's to .flac by default. However, that selection is not consistently retained by the program, which will somehow revert to one of the .m4a codec options without me having selected it. I'm not sure what triggers the program to revert to .m4a. It may happen after changing CDs, restarting the program, or rebooting my computer. I haven't been able to identify when it happens because it is not consistent, and I never catch it before ripping at least several CDs with the unintended .mp4 codec. I realize that it should not be much of an issue, since the codec selection in use is always visible while ripping a CD. However, it would be much easier if the program retained the codec selection consistently, so no vigilance is required. I assume I have not been the only user experiencing this. Sorry if this topic has been covered already.
