Problem with items not appearing properly

In the above you can see a picture of a file I’ve created with libreoffice writer.
The specific file contains equations created with the build in math equation creator.
My operating system is Windows 7 64 bit with service pack 1, my default language is Greek.

This problem appeared yesterday, after I was trying to enter a picture into one of my documents.
Since then, any file containing items, whether they are images, equations or even dots/numbering of text, they appear like blank boxes.

After this happened I uninstalled libreoofice, I cleared my registry with ccleaner and installed the latest version of libreoffice but to no avail…
However, when I click on the print preview button everything is shown properly, including all images and items.

Anybody with any information on my problem, please help :slight_smile:
Thank you for reading!

I don’t quite understand that RFO thing…
But I was able to find my answer here
