Yes. Theses instructions from Priyanka in a comment below do not work for me:
"
1. Launch Preferences dialog.
2. Select Commenting from Categories section in Left side.
3. Uncheck the checkbox for "Show comments pane when a PDF with comments is opened.
"
The checkbox was unchecked, I closed and opened Acrobat, the pane still auto-opened, the checkbox is still unchecked. Repeated steps, same result.
