I have several pinned programs on my taskbar in Windows 8 such as Chrome, IE, and even the Documents folder. When I start any of them, they open on the same location where the program is pinned. The icon just gets "alive" so that I can recognize that the program is running.
However, I pinned Eclipse there too. But when i start Eclipse, the application appears at the end of the taskbar line. Note that the pinned Eclipse icon stays on the taskbar list. So when running Eclipse it takes two positions on the taskbar. How can I make it behave like all other programs?
I noticed this too and the solution in my case was to unpin the "old" icon and pin the "new" that appeared after starting Eclipse, this worked for me.
