It appears that Hyperlinks are behaving oddly in PDFs exported from Publisher (1.8.1)
A hyperlink added to a word works fine.
If the hyperlink is added across several words, then it is fine.
However, when a hyperlink added to several words and those words are split and carried over to the next line, then the hyperlink is applied to the whole of first line and the while of the second line. Not just the 'underlined' words.
This becomes a bigger issue if there are two different hyperlinks and the second one is split over two lines, then the first one is ignored and takes the hyperlink attributed to the second run of words.
The only way I found around this was to explicitly add the full URL and not assign it to a word.
