Audition 2020 13.0.9.4.1 - Catalina 10.15.6.

When opening multiple files at once, the warning/error dialogue box automatically disappears after the last file is opened making impossible to read the error or multiple errors (missing files, missing plug ins etc..).

Currently the only way to make the warning to work correctly is to open one file at a time.

EDIT: today, same sesxs, same machine and files, the problem is disappeared. I'll report here what could have influenced Audition. Please Adobe verify anyway my report. Thanks.
