I have to type in English (no Chinese input on this sytem):
Take IE 6.0 for example:
Click on Tools menu, then click on Internet Options...,
on the pop-up window, click on Security tab, pick Internet icon, then click on Custom Level... button. Another window will pop-up, make sure that "Run ActiveX controls and plug-ins" and "S*c*r*i*p*t ActiveX controls marked safe for scripting" are set for "Enabled" under "ActiveX controls and plug-ins". Also, move down to check Enable for "Active scripting" and "Scripting of Java applets" under "Scripting" too. Click on OK to close the window and OK again to close the previous window. Try to see if it will work for you. By the way, some organizations ban internet email sites, so that may be a cause too.
