I just have a machine with Win7-SP1 64bits and IE10.
When I have a mail with a link (ex: Powerpoint show) and I push Download, the file is always directly downloaded to my machine.
On my previous version I become a window where I can select between Open and Save.
Pushing the Open button the powerpoint show was started without first downloading to my computer.
Is there a way to get back this window when I select download on a mail attachment.
