I'm using Office 2007 in my laptop with the operating system as Win8. Usually, several Word windows can be displayed at the same time. While, if I open several Excel windows, only one of them will be displayed, and that is the last opened one. And if I want them to be displayed on the desktop at then same time, I must click icon in the task bar to change over. But after changing over, the former one can not be seen.
How can I set the windows of Excel as those of Word?
