Manually moving the task bar leaves a ghost image along one of the respective borders from which the task bar was moved from. Here's an image. Notice the left side of the desk top. http://picasaweb.google.com/tsball/ HiThis is a known bug and has been reported many times.It appears to occur on systems that have certain hardware combinations.There is no fix at the present time, except to move the Taskbar back to the bottom of the screen to remove that ghost image.Hope this helps.Thank You for testing Windows 7 Ronnie Vernon MVP
