remove application shortcut from Unity panel
First a small note: my Ubuntu installed not in English language, so I could be wrong in names of some GUI elements.
In Unity menu (the on that appear when you click "Super" or Button with symbol that shouldn't be named here), when I make a search for a program I see there an icon of old game, probably dos game, or early win game, which I some years ago tried to install on wine or maybe not (not sure about fact of appearance that game on my computer).
The problem is that I cannot delete that icon. I cannot found this app in my package manager, I even uninstall wine, but it still there, and the strangest part, when I click on that icon - nothing happens. I tried to search my computer for the files with that name, but with no results.
Is there any place where program can hides in my computer, but be visible for this unity app search?
