Re: unkonw problem,need help
Being able to access a website but not login usually means that cookies are not working. Some email sites also require Javascript. So make sure both cookies and Javascript are turned on in the browser settings.
I also suggest when using someone else's computer, use a flash drive with "portable applications" on it. Then you can just plug it in, do your stuff, then remove it when done, and the computer will be exactly as you found it: nothing else installed and no settings changed.

why not just have him use ie or FF...
Re: unkonw problem,need help
you can use chrome as well :-)
Re: unkonw problem,need help
The portable application suggestion is very good. I myself carry a usb flash drive(to work etc) where I have to login to multiple PCs to use them.

Ultra-customized portable Opera here. Won't leave a trace on the computer it runs on.
