So basically when you open Internet Explorer and then you click on the I.E. icon to open a second window nothing happens no response, no errors and the first window still works?
First step, download and install Firefox so you have a second browser that you can use tabbed browsing or more than one window.

Second Step,
Check your system for Spyware, Malware, Viruses. Run a chkdsk, defrag, clean cache, temp files (recommend
