Recently did a full install of Professional 8.0. Existing PDF files open OK, but 'blue bar' at top of screen identifying file name shows only the 'Acrobat' logo and the first letter (not word) of the file name. Upon closing the file, the 'blue bar' continues to show only the 'Acrobat' logo and the letter 'A' (presumably the first letter of the words 'Adobe Acrobat Professional', which normally appears in the blue bar when Adobe Acrobat Professional 8.0 is running, but no files are open. Thoughts? Suggestions? Thanks.
