A user invokes "Import HTML" and selects an invalid file for importing (if they browse for it), or types the path to a file that doesn't exist (they don't browse for it), results in a "Cannot Import from File". A user invokes "Open Page" and inputs an invalid path to a Page (they don't browse for it) results in a "Page Not Found" error. All of these errors result in an error message box generalized in Figure 2.8.4a.
