On any web site if the text is too small, just hold down the CTRL key and press the + key. You can do that multiple times until you get the right size. OTOH if you get one that's too big, you can shrink it with CTRL-.
There is one web site I visit regularly that on one computer I use the text and everything on the page is loading microscopically small. Any other computer I use, this is not the case. Also, the computer with the small text, it only occurs on the one web site. Any ideas?
