HI
Problem is whenever I open my gmail account I get a continuous loading in FF with a "page load error" after a long wait. I open it with IE7 and it works. Strange thing is a user comes to me this afternoon and tells me she also cant access her gmail but shes experiencing the problem in IE7. Now what? I'm slightly stunned.
Any Ideas?
Thanks guys
