How to refresh an access token every once in a while?

Most times when I attempt to access my yahoo mail, I get a blank screen. Even F5 refresh won't work. Why?

• My ISP is AOL 9.0. I have spyzapper and an aol security and safey program installed. System memory is supposed to be 1024MB but that has not been verified.

• Answer:

  if you are using the beta version do what i did switch back the beta has way to many issues wait until its ironed out as for system memory right click on "my computer"icon and on properties that will give the computer information if it shows less memory then make sure all memory is seated properly(with the computer off of course LOL)then you will know for sure but i doubt that has anything to do with the trouble getting your mail(assuming thats what you meant by system memory and not mail box capacity!!good luck hope this helps also get a differant browser to get your yahoo mail aol is to slow for that i use fire fox here is a link to download it http://www.mozilla.com/en-US/ i have always had good luck with it and it is a lot faster for web surfing also!!!good luck!!!!
