Hello

In BIAB 2021 for Windows, there are sometimes actions on the management of the tracks which do not succeed, while no error or warning is sent to the user.

I imagine that these errors are "normal errors" which can be explained by the fact that some business rules are not satisfied. BIAB therefore refuses to do so.
But it would be good to signal by a msg that the action is not possible because of this or that reason.

This would avoid retrying the action several times or making a support call for nothing.

For example, copying from the Audio track to the Melody track does not work, without further warning . I take this example because it is the last one encountered, but there are other cases where BIAB does nothing, without explaining why.



Thank you for your attention and best regard.
