I don´t know if escargot will do this
MSN/WLM uses Internet Explorer by default, you can’t change it.
Also, MSN Explorer is a old browser that was been discontinued years ago, it would not load any of the tabs correctly.
IE can´t open all of the pages
If IE can’t, imagine MSN Explorer. 
that´s right the MSN explorer can´t i think that other explorer will be right
MSN Explorer is not discontinued, see this thread
He probably was talking about MSN Explorer in Windows XP, which did not require a subscription. That one was discontinued years ago and is not able to open any current website.
The one you refer to is a paid service from Microsoft, still updated, different from the one mentioned by Lapras.
that explorer still needed an msn dial up subscription iirc
IE 6 5 or down confirmation
