Having problems with IE7. I will click on a link and IE7 will display a blank white page with the word Done in the lower left corner. If I click Refresh, usually the page will display. Sometimes I have to click refresh several times to get the page to display. This issue is repeatable at several sites. When I connect to eBay and when I exit Yahoo Mail it happens every time. A co-worker has the same problem with Google Maps. After she sets the start and end points and clicks Next, she gets the blank screen. Any thoughts on what to check?
