Yahoo mail check all option has disappeared?

Maybe if she signs out of her account, then restarts the computer it might come back. In the New Mail it doesn't say check all, it says Select all, but on windows 95 I don't believe she has the new mail. It's difficult, next to impossibe to load on older versions because of all the upgrades it needs. I have not encountered this happening to anyone else. Yahoo may be in the middle of upgrading her clic mail, which will cause glitches in the beginning. I had things not appear at first, but then it resolved itself.
