Spilt something over my wireless keyboard the other day. No damage done - but, when the spill happened I grabbed the keyboard and would have pressed a stack of keys while soaking up the worst of the tea. This caused something to change in my display settings. I am buggered if I can return it to normality.
Hard to describe, but in order to have the text on a webpage displaying at what seems to be the correct size, I had to Ctrl+ a couple of times. But when I do that, all the images on the page (e.g. the yacf logo top left) are too big when the text is normal.
Resolution is at the correct setting.
