I am running Windows XP. When I launch Internet Explorer, with Google as my home page, the toolbar is all white, and the body of the site is all black. I can't see the cursor, but if I start typing and hit enter (as in the Google search box) I can see the page change but the background is black and white but still no words or images. The same problem happens in Mozilla but in reverse. The Google page is all white and Mozilla image (fox on globe) is on the top of the page. If I type in the Google search box, I can't see the cursor or letters I'm typing, but when I hit enter, the page changes.
It appears my background is inverse and so is the color of my font (I'm typing white on white or black on black). I'm not sure where or how to correct this.
