When I used to open attachments there was always a drop down box asking what I wanted to do. Such as download, open the document or save the document. There was also a box to check if I always wanted to do this. I almost always want to open the document. But one time I downloaded a document and inadvertently checked the box to always do this. Now I want to open attachments but they always download and I can't find out how to change this. The drop down box no longer appears.
