Hi, I have a problem in last couple of months :(
I have Windows 8.1 and have Intellij Idea, Android Studio and PyCharm installed on my system.
I have launcher icon of each of them pinned to my task bar.
My problem is whatever application is running PyCharm will be selected as running application.
For example, Intellij Idea is running while PyCharm has been selected in taskbar.
Please look at following screenshot.
