Error: There is a serious disk error on <filename>.(due to empty box after drag)

Error:


'There is a serious disk error on <filename>.'(when double-clicking an empty box that appeared after dragging and dropping an object from PowerPoint to Word then saving Word and reopening)

Cause:


Dragging an object leaves an empty box.

Solution:


To preserve the object, use the 'Copy' and 'Paste' commands to copy an object from PowerPoint to Word, INSTEAD OF dragging and dropping.
