I need help with a new problem. When editing a document, suddenly a blue frame appear around the document text. It prevents me from any further editing. The curser jumps anywhere when an edit is made. The Tab button jumps to info outside of the text area. also make blue frames, e.g. (top of the page) tab settings one after the other every time the Tab button is pressed; (to the bottom of the page) page 1 of two; 805 words; I have to close the document and reopen it.



I am using Word for Mac Version 16.78 on M1 MacBook Pro. I never had this problem before. It just happened 3 days ago and so far I can not get a solution on the web. Interestingly, it does not happen while I am typing in this section.

I have reinstalled Office 365 three times already but the bug persists.
