I use Mail.app on Lion with Classic View enabled so it works like it did in Snow Leopard.
When an email comes in with an attachment, I used to be able to select one or more attachments and drag them to my desktop. In Lion, it looks like I have to click "Save" and then choose a location for the file.
How can I drag and drop email attachments in Lion?
If the answer is I can't, then can someone explain why the change? Having to click the "save" drop down, click an attachment, choose a directory in the pop-up, and then click the "save" button is much more work than drag-and-drop (and it feels decidedly Windows-esq, frankly).
