Hello Chanlin,
Please always state what OS you're & service pack and what
version of Internet Explorer? as it often does make a difference -
Also, could you supply some information on what your firewall is, anti-virus,
other R-TP programs, e.g. Spybot Search & Destroy (reduced functionality
called "TeaTimer"), Ad-Aware, etc?
