In Office 2000 & 2003, I could open several different Excel or Word files in the same application window - not all at the same time but where just one is open "on top" and the others are reduced to tabs in the task bar that can be selected to open the file I want to see. That was easily arranged with Tools - Options - View Tab - uncheck "windows in task bar". Now in 2007 & 2010, every time I open another file, another whole version of the application opens. When I close a given file, the application with that file stays open so I end up with many tabs of empty Excel or Word windows at the bottom that I have to close. They don't close when I close the file. Is there a way to make 07 & 10 versions of Office work like that? I'd like to be able to open multiple Excel files (not on the same screen but like I described above) with just opening Excel once so when I close the last of the multiple Excel files, there are no remaining Excel tabs open in the bottom. Thanks!
