something not very right with my yahoo email

I just cannot figure out what is wrong with my yahoo account. Been trying to get into my mailbox but once it logs in, the window will hang. I can still re-open IE n get into other websites but it is only the yahoo tt is giving me problems. Tried it on the other computer n have no problems. N i dunno y the network seems to be so slow. Takes ages to open pages. N it is very inconveinent to have to change email addresses cos tt means having to inform EVERYONE n tt can be a real pain in the neck.
