Sure this is a dozy question but here goes:
I have a Toshiba laptop using Vista OS. Sometimes when my hand is ested on the keyboard somewhere the font size reduces on the page I am on so that it is barely legible. If I come out and go in again then the small size remains. It does it on the particular site I am on, not all pages/tabs I may have open. Problem is I can't recreate the issue. I thonk it is something to the 'mouse' bit and probably touching another key.
What am I doing and how do I reverse it?
Thanks, a technoclot.
