One specific issue I'm stuck on; a very small amount of people using Yahoo Mail can not read forwards I send from NS 4.79. This only impacts Yahoo. It does not appear to impact Firefox; so it may be some clash between Netscape, Yahoo & whatever non Firefox browser these folks are using.
Does anyone have any knowledge of this issue?
