I have a problem with Lotus notes 8.5.1 wanting to open certain emails in my web browser, rather than within Notes itself. The emails that do this, seem to have some html in the note (Not just a link, but the note itself) This is a recent upgrade from 8.0.2 which had a similar problem, but it showed all of the html formatting characters in the notes, rendering it almost unreadable. I was hoping a fresh install of Notes would fix it, but it did not.
I am using the same version of Notes & Win XP at work, and I do not have the problem. I am guessing that it is a setting on my home computer and not Notes, but I have no idea what it would be.
