hi, i'm having a problem with thunderbird lately. it only effects my 
hotmail account and not my gmail and yahoo accounts. every so often all 
the email in the account will disappear and then redownload. also when I 
try to read a message with the down arrow I get a ding and window eyes 
says blank document when theres something there. does anyone know how to 
make it stop doing this because its getting annoying. thanks
