Using a quote from Matt Finley in another thread that he wanted answered here:

"Jcland, yes, I see the other thread. I also see a lot about frozen tracks not working. You said your are not frozen, but is that NOW or EVER? Don't answer that; let's pick up in your new thread."

Matt: The scenario in my initial post shows that using the Freeze button on the Main Menu acts different then using the Freeze button at the bottom left of the mixer. Please read it again and if anything I said is still not clear, let me know and I will try and clarify.

But to answer your question on the quote: The tracks I un-froze were initially frozen and save in the past.

Try this: Load the style _GUITBLZ.sty and load its associated demo. Initially nothing is frozen.
Now freeze then using the Freeze button at the bottom left of the mixer and what I see is the 4 tracks being used show frozen but the blank tracks do not change state.

Now quit BIAB and don't save and restart BIAB and go through the process again of loading the style and it's demo song but this time use the Freeze button on the main menu. I see it freezing everything including blank tracks.

Finally if I load a previously saved file that had ALL tracks frozen and try to unfreeze using the Freeze button at the bottom left of the mixer, the tracks that are being used get unfrozen but any blank tracks still have the frozen indication.

Any previously saved song had ALL tracks frozen and try to unfreeze using the Freeze button on the main menu, all of the tracks regardless of them be used or blank, all show being unfrozen.

The two methods act totally different and I can definitely tell you that was not the case using BIAB 2021 back at the end of November. I still have both versions on my SSD and just tested both 2021 and 2022.
