I was particularly referring to Office applications which have a first stage save dialogue with some folders shown but if you want to navigate to another location you need to browse which opens another window. In the physical office metaphor this would be having to change your shoes to look in a different file cabinet
Oh I see, I hate the new UI of Office. I somewhat accept the ribbon, but this new full screen file menu replacement where they try to make you save stuff to the cloud makes me want to go back to the good old File > Save as... > Dialog popup of Office 2003.
