Yesterday I hit a javascript error as per screenshot below. It only happens when I try to open a popup window. This is not due to the web page error because I tested in other machine with the same version of browser but no error occurs. After I tried so many solutions and finally find this get the problem fixed as below.

1. Open registry file (Start – Run – regedit )
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent\Post Platform
2. Look at the right pane see whether is there any funny field appears. I get this funny field in the registry on the last list; I copy the value name and value type only then delete it to safe from deleted wrongly.

Note: I will not responsible for any damage of doing this modification.
