It was late, and I was a little tired, but that's my current theory.

Assuming this is the case (will test a bit more later), I should probably post on the MP3Tag forum - it would probably be desirable for a tag delete to delete everything apart from the vendor tag, right???

5. Now, if I create a FLAC using Frontend but without adding tags I get "1.1.2" ... But if I have the add tags check box ticked I get "1.1.0". So it's only when you add tags that it happens (for me at least).

Have noticed though that FLAC seems to set the last modified date to that of the original WAV. Again, no big deal, but it meant the files were not backed up/copied to my slim server, as the software I was using only checks the file mod date (not the creation date). I just resaved the tags using MP3Tag, bit it *may* be good to set the mod date according to the encode time (am thinking that as the tags have been added the file has effectively been modified).

maybe flac frontend statically links with libFLAC? (I thought it just called flac.exe).

If it is using Case's original then there is little hope of a change.

I have just compiled 2.0.48 to use libFLAC 1.1.3.
