Yahoo access from W98 recently

Within the last couple of days, I and others I have spoken with cannot access Yahoo from our orphaned W98 systems. WXP access is normal. The home page loads sort of, but never completely. Can login to mail, but cannot get to mail page. Yahoo just keeps trying. Since several of us have the problem, we suspect that Yahoo has made a change to affect IE on W98. Any one know anything? I will try to ask Yahoo when I can get to a WXP system.
