Why is there some browser history left after erasing ?
You should close all the browser windows before erasing, because the files can not be erased when they are in use. For MSN, AOL and Netscape 7, even you close all the windows of them, they may not close completely. Please check the system tray (lower right area of the screen) to see if there is an icon of them, if you can find, click on it to close it.
