I read your article "Remove Microsoft.mshtml dependency". There is a piece of code, which was very helpful to me: implementing FindNext method (by using Microsoft.mshtml).
Could you please write a similar method: FindPrevious?
I tried hard to derive it from your template but no success.
I posted this problem also on http://stackoverflow.com/questions/3588350/webbrowser-find-previous-text
There is not much about this topic, surprisingly...
