It appears there are two ways of specifying the default browser (the one to use then clicking a link in an e-mail) in Notes 8. One is on the “Internet Browser” tab of the location document and the other is on the “Web Browser” preferences page (see File/Preferences). The actual browser used to open links is the one configured in the preference pages.
I found this strange so I digged around a little and I found the cause. The problem was that my personal name and address book wasn’t upgraded to R8 design when my client was updated. This in turn meant that the location document form didn’t show the help text describing this. After replacing my design I found the problem and could correct it. So when moving your users to Notes 8 be sure to upgrade the design of their personal address book.
Good thing it’s Friday!
