But, what if you want to launch a second instance of the program ?? There is a no way out to do this because when you click on its icon, you only switch to the running instance.
There is a simple fix: If a program is already running and you want to launch a second instance from the taskbar, hold down the Shift Key and click the icon. A second instance will launch. Another way out is to right click the running program icon in the taskbar and then again click the program name. You can keep launching new instances this way.
