well, since few last months, whenever I open IE and then close it, a pop-up comes with the message "Internet explorer has encountered a problem and needs to close. We are sorry for the inconvenience." And if I open it for a number of times then the right click feature stops working and the PC ultimately gets hanged. Even ctrl-alt-del doesnt work. I use some share trading softwares and the pages which open through it opens up directly in IE only. Hence the compulsion to use IE. Pls help.
