I still get that result in I-explorer but also use "CTRL + -" a lot. Perhaps you are correct, I will try and be good about zooming for a bit and see. But I need to use zoom as I wait for the cataracts to be bad enough for the specialist to decide to operate.
I don't really worry much about the system going back a few pages though, I simply scroll down with the mouse wheel. Think I shall also go back to Firefox.
