The message content of my incoming emails has suddenly downsized to about 6pt, which I can't read. How can I increase the size of the print?

Messages shown in print which is too small to read (about 6pt)  

Hi Judith.

Easy to correct. Hold down Ctrl and scroll the wheel on your mouse forward;  increase
or use Ctrl +  minus -  or  plus  +   keys to change ;   decrease or increase the font.
