They're the settings I was on but it didn't make a scrap of difference.
In the end I contacted Dell support and someone took over my computer and fixed it.
They went on the stting described above but then went somewhere totally different (no idea where or what she did - it was so quick) and instantly things were almost back to normal.
The only things that don't look right now are the background colours of the taskbar (at the very bottom) and the title bar(? - where all the tab names are at the very top). They're a very dark blue which I'm sure they weren't before all this palaver.
What background colours does everyone else have for these bars?
