Acrobat DC - sidebars permanently off

MOVED TO THE ACROBAT READER FORUM

Hi Peter,

Thanks for sharing the screenshot for better understanding.

What you are referring to is a Tool-pane. The screenshot shows that the application you are working with is Acrobat Reader DC.

You can disable the Tool-pane permanently, following the suggestion given here: https://helpx.adobe.com/acrobat/kb/disable-right-hand-pane-in-acrobat-reader.html 

Also, Navigate to Acrobat>View>Show/Hide>Tool Pane and uncheck it

You can keep the "Restore last view settings when reopening documents" under Edit>Preferences>Documents

Thanks,

Akanchha
