Two weeks ago, I bought a New computer with Vista Premium Home version OS. The computer uses Intel's Core 2 Quad processor. Though I primarily use Firefox, I occasionally NEED "Internet Explorer"as my web browser. Recently, Internet Explorer has failed to open/load and I receive a dialog-box with the message, "Internet Explorer has stopped working." It offers buttons to either "check online for solutions and close program" or simply "close Program." In the "Details" section below, it lists the problem as being "APPCRASH." Note: Firefox opens/works fine and I can open/load Internet Explorer, when opened as "Administrator." Yet, logged on as "User" Internet Explorer will not open, though privileges are AVAILABLE and NOT blocked. What is Wrong and how do I fix this problem?
