As of this morning, when I close my open PDFs (using the X that appears when I mouseover the Windows taskbar), closing the final PDF does not close Acrobat itself. Instead it takes me to the Acrobat home screen.

I don't want this. I want to close Acrobat when I close my final open PDF. I don't see why anyone would want this behaviour, but even if some do, please make it an option (as it has been in the past) to close Acrobat completely when I'm done with my final PDF.

This is an unhelpful and anti-productive change.

EDIT - one thing to add. I just noticed that if I close the PDF using the X in the top right of the open window, it DOES close Acrobat as expected. It's just when I close from the taskbar that the homescreen is shown. And in fact, it only happens when the window is open, but I try to close from the taskbar. The window does not need to be at the front of my open windows, it can be open but hidden behind something else. However, if the window is minimised and I close from the taskbar it works as it should.
