I have just carried out a defrag with AusLogics for the first time and the next time I booted up I noticed that the top of IE7 which shows what site you are at is now black and I am sure it was blue before. Also the address bar is now grey and I am sure this was white before. Office 2007 also appears to have turned black at the top of the screen.
What's going on?
Is it reversible?
System Restore is not an option as it hasn't worked reliably for months!
