What a Pain!!

I have a paid mailbox and a free mailbox, both are yahoo.

Whatever they did to my PAID mailbox, with the little green box that
opens everytime you click on something, that shows it's loading, it
has become very slow, and sometimes, even immovable, especially if I
click on delete, which is often a necessity, needles to say.

My free mailbox moves at lighting speed ***all the time*** even with
the pop up ads.

Anyone else experiencing this?

What gives?

Thank you,
