Some time ago I set up my standard project template with folders for various instruments. I created each folder and named it appropriately.
The renaming function seems, however, to now not work. I can create a folder but now cannot rename it. Something appears to have changed.
Also, related to this, the only way I have found to rename tracks or folders is in the inspector. The manual appears to clearly indicate that you can double click on the track name and change it that way but this has never worked for me.
