In XP/Vista, when a program was open and active, you could minimize it by clicking on that program's name on the taskbar. For example, with an instance of Firefox open you could minimize that instance by clicking the same thing again. In 7, this still works, but only if you have one instance of the program running. So, where I have two or three Firefox instances open, you can't minimize from the taskbar anymore - because when you click on the icon, the window preview comes up, and if you click it again, nothing happens. Has anybody found a way around this?
