Acrobat Reader DC grabs files
Acrobat Reader is the ONLY program on my Windows 10 computer that thinks every file icon dragged over it belongs to it. Let's say I'm trying to drag a Word document from Windows Explorer to an Outlook E-Mail that I'm composing. My desktop is large (55 inch 4K monitor) often with 10 or more apps open, and I may have to drag across most of them. If I don't consciously avoid Acrobat Reader, it will move itself to the top and assert the focus. As I continue dragging past it to the destination, the file may or may not reach Outlook. If it does, it will take several seconds while Acrobat Reader is trying to "claim" it. In most case, it is a file type Acrobat Reader can't handle anyway, so if it does grab it, it will fail.
