With lots of document readers (okular, xpdf, skim, ghostview) the viewer will reload a document if it is changed. Can acrobat reader do this?
Ubuntu linux 9.04, acroread 8.1.3
acroread does not support it. The PDF reader Evince (Document Viewer), which is installed by default, automatically reloads if the file it is displaying changes.
Current Adobe Reader 9.4.2 allows you to press Ctrl+R to reload an opened PDF.
