I've been using TT for over a decade, and this is the first time I've encountered "The disk TT 2023" wasn't ejected because one or more programs may be using it." I've already installed the application and have already started a return, confirming the information is unchanged and about to start the "wages & income section".
I force-ejected the CD, and the program is still running just fine, at least so far.
Has anyone else had to do this? Any problems?
