How do I fix this problem with Windows Internet Explorer 7? -

The problem is that when I close one window, all the other windows and Internet Explorer closes as well. It is quite frustrating to go on and off several times while visiting just one site (which may have links that open up in different windows).

un-install and re-install Your Computer/laptop may not meet the system requirments causing problems with it.

Ok just click the right side of the mouse from the bottom, on one item at a time. When box pop up tell it to close.

Un-installing and Re-installing is a good bet. Also, run a virus/spyware scan.
