Used this a tremendous amount for years and it has worked very well.
Suddenly it has developed a silly habit.
It insists on its default settings in its file dialogs such as the SAVE and OPEN dialogs. I can change the layout settings as much as I want but the next time I open the dialog, it has reverted to the default layout.
Something has gone wrong, it never used to do this - is there a cure for this?
Probably the easiest thing for you to do is to re-establish the defaults for Audition. You need to reset the application data files according to the information in this FAQ. There's a good chance that this will stop this behaviour. If for some reason this doesn't work, then uninstall and reinstall the software - although this is in extremis - you shouldn't have to go this far.
