I think you don't really understand what I was saying.
Messenger Plus Live! is not made by Microsoft.
The Browser Control that is build in Plus! is only working for the contest and the only website that you can browse to with it is the contest page.
There is no 'normal' browser build into Plus Live!
The 'MSN Today' browser is a part of MSN / Windows Live Messenger and not Messenger Plus Live!|
So to kinda answer your question.
The Useragent of the MSN Today window is:
code:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; Windows Live Messenger 8.1.0178)
EDIT: So as you can see this is simply a edited version of the MSIE 6 useragent with the added Windows Live Messenger version tag.
EDIT2: As comparison, my MSIE 6 useragent string:
code:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)
