I haven't noticed any problems with Yahoo! mail.
As to how to fix your page view problem, try clicking on the "cogwheel" icon in the upper right and playing around with the settings and other options.
It works as poorly as it always does. Gotta love consistency.
Yes, Yahoo Mail has been very slow for me recently. I use it as a secondary "sign up" address. I am worried that Yahoo may go down the tubes taking that account with it. On the other hand, my throw away account with Excite has kept chugging along for decades. Maybe these outfits never die.
