Equations as "picture"

asked 2016-09-16 00:33:34 +0200

so sometimes I open a document and previously entered equations are just pictures, as in I can't edit them anymore. double clicking on them doesn't allow me to edit them, also from Edit -> objects is grayed out which should allow me to go Edit -> objects -> edit

so I'm wondering how I can avoid this.

These "equations" most likely were not created with 'Math' (but probably with Word / MathType). Since different formula editors are not expected to be compatible, you will see a kind of preview image of the formula that was created with the alien software.
