As of Sunday 11-17-2013 my Windows Live Mail has stopped allowing me to open any attachments directly from my emails including pdf, docx,  and excel spread sheets.  All have been from trusted sources.  I right clicked on the attachment icon and it will not Open or Print.  No error messages, just won't open.

The only work around I can find is to right click on the attachment icon and choose "save all....".  I can then save the attachment to my desktop and open it from there.

I am confused since I did not change any settings in Windows Live Mail and I could open the same attachments last week.

How can I change the settings so I can go back to opening the attachments directly?

Thanks
