I'm using Windows 7 Ultimate and I have a lot of browsers installed on my system (Opera, Firefox, IE8, Safari, Chrome).
But whenever I start any of these browsers (except Firefox), my taskbar freezes completely. I cannot access anything on the taskbar including the start button. After pressing Ctrl+Alt+Del, I select 'Start Task Manager', but that also freezes. The system only comes back to normal when I close the browser window.
Suprisingly, Firefox is the only browser which works perfectly without freezing the taskbar. I've Firefox 3.6.8 as well as Firefox 4.0b5 installed and both work without a problem. Any ideas?
