Publish to Folder fails silently if destination folder does not exist

If the destination folder for "Publish to Folder" does not exist, the "Publishing Setup...", "Publish to Folder", and "Visit Published Site" operations all fail with no error message, warning, or other explanation.

To be specific, "Visit Published Site" does absolutely nothing, while "Publishing Setup..." and "Publish to Folder" both bring up the same dialog box wherein you choose which method to publish (MobileMe, iWeb, FTP, Folder), what to publish (Everything, Selected Shelves), and the template (Paper Stencil or Library Shelves), and an action (Publish Now, Done). In my case, Folder is selected, and nothing there indicates that there is a problem, but choosing the "Publish" button simply dismisses the dialog box.

This came about because I'd last published to a network volume which was no longer connected, but it could have been for any number of reasons. In fact, I'd forgotten that DL2 let you specify the output folder name, as it's hidden away under that little (i) icon, and was just assuming it would put it in the default location as it had the first few times I'd run it.

Delicious Library should:

1) Avoid this by having the current destination displayed in the "Publishing Setup" dialog box, preferrably right under the line of buttons indicating different destination types, and

2) Explain the problem with an error message box if the publishing operation or the Visit Published Site operation fail.
