Locked shapes, objects, images or tables in your PowerPoint presentation can be unlocked using PPT Productivity.
Select the slide/s containing locked shape(s) you need to unlock, then click 'Unlock objects' (Found beneath the Lock Object icon on the PPT Productivity Ribbon).
The file will close momentarily and reopen (you do need to first save your document to a local drive). Previously locked objects will then be unlocked and can be moved and edited like any other shape or image.
You need PPT Productivity installed to unlock any shapes, objects, images or tables that you have locked (so if you lock a shape it will be locked for anyone viewing the presentation without PPT Productivity installed). Only users with PPT Productivity installed on their machine can then unlock the shapes.
