Zahid, Go into Internet Options>Advanced tab, under Browsing uncheck "Reuse windows for launching shortcuts", click Apply/OK. It may correct the problem.

I am using I.E Version: 6.0.2900.2180.xpsp_sp2_gdr.050301-1519 over Windows XP professional version 2002 service pack 2. I have noticed a change in I.E behavior. When i try to open up a new instance of I.E it immediatley closes down the existing open window and opens up a new window. This obviously results in the loss of entire data. Now i can't use multiple instances of I.E which i used to do. I am highly frustrated due to it. Pls help me to fix the problem. Just to let you know that i have updated antivirus, anti-spyware and a recent version of Zonealarm installed at my system.
