Adding new LIST-INFO chunk corrupts file

[jamsoft]

This is more of a question than an issue.

I'm currently looking at the InfoTag for WAV files. Opening a file with an existing LIST-INFO chunk, editing the values and saving the file works fine. No issues.

I can open the saved file in BWF MetaEdit / RIFFPad and see the changes. I can also re-open the edited file and see the values without issue.

Doing the same with a file that didn't originally have a LIST-INFO chunk seems to monumentally fail.

BWF MetaEdit regards the saved file as corrupt and RIFFPad cannot even see the LIST-INFO chunk. Whereas in a binary editor I can see the data but it's appended to the end of the file and something is clearly wrong with the binary data.

I'm still trying to figure out what is wrong with the saved file and not having much luck.

Anyone got any info on this situation?
