I have machine that runs on Windows 2000 and has IE 6.
A couple of months ago, when I tried to open a new window by using the "Open in New Window" option, it opened the new page in the same window. It has been behaving like this ever since. I checked the Microsoft knowledge base and it had the following remedy listed there.
I repaired the registry entries but to no avail. I have not tried to repair or reinstall the operating system.
Does anyone know of any other solution or is my only recourse repairing the OS?
