This may seem trivial, but it drives me nuts. I have a document folder on my desktop that ends .dll When I click it to open I get the message; there is no default application specified to open the document, choose application. So I click choose and get a menu with two selections, recommended applications and applications shown. No matter what I select, the open command at the bottom of the menu stays greyed out and I can't open the document.
What am I doing wrong?
