gouri... have you fixed your problem with IE7?
Thank you for asking me about this.
I also apologize to everyone for not posting earlier.
For a couple of days I ran it with no add-ons because with the add-ons I could not close the browser. After a couple of days I used IE7 with add-ons and I was able to close the browser.
I guess one of the add-ons was causing the browser not to close and it must have been fixed. I am mentioning this because I didn't add any the day I started having a problem closing the browser or around that time.
Thanks to everyone for the helpful information.
