mac people - dd1 has managed to turn her screen negative

[Cappuccino]

feck knows what she pressed

it was black and white negative but now we have managed to fiddle with it so it is colour negative - big improvement (not)

what did she do?

I know the monitor is working because the start-up comes up all proper blue and white

but then as soon as the desktop loads it is odd

we have fished through system preferences to no avail

I must remember that to do to people at work I don't like

you're a lifesaver she has been looking at this odd screen sadly for days
