Got day off work, then decided to clear my desktop 
& on doing so my mouse fell over the edge 
& while grappling with it so it didn’t hit the floor I must have pressed something that has altered the text size 
& made the text realy quite large( like across the room readable large) Does anybody have any ideas on how I can reduce the text size back to normal please 
I have tried through the main system & no joy 
It’s a vista), ideas anyone please 
If you just mean on Trucknet, there is a text size selector just under the title bar underneath contact us.
If you mean in general either press CTRL and Zero together or simply reboot
Are you talking about browser text or another program ?
For Browsers:
Firefox menu bar - View/Zoom/Reset
Internet Explorer menu bar - View/Text Size/
Whatever program/Browser try the keyboard short-cut Ctrl + (plus)+to enlarge the screen image/text size or Ctrl + (minus) - to reduce the screen image/text size.
Hey many thanks you guys, got it sorted - what a relief to the eyes
