text becomes pages of these *** and then coding

[EkkoJohnny]

This happened once about a year ago, where the document just went berzerk and all the text tuned into pages of ******** then into squares with letters in between.



I can recover to a certain point, but this is really crazy.

Any idea what's causing this?

I'm typing when it happens, editing and basic stuff. This time I typed in brea (for the work break) and before I finished the word, the document wigged.

big thanks if someone has a clue of what's happening, and even better if there's a way not to lose the work.

Thanks
