Hi there and welcome
Can you hold the CTRL key on your keyboard and press + and this should then increase it for you.
Do this when you are looking at the text.
Let me know the results please
Mary, you obviously have a different issue on your computer then....
I have not left, I am here and willing to work with you on this.
Such a response is not necessary.... if you just want a refund you can request one
else can you tell me which internet browser you use to access Gmail please?
