I just wanted to say that I also have noticed this for some time and it's a very annoying bug since you basically have no choice but to close Notepad++ and reopen it otherwise you keep getting a "Find In Files" dialog window in the task bar every time you do a search.
Ordinarily this "Find In Files" window should automatically (or manually if the search takes a long time and you click the button in the window to cancel the search) disappear when the search results show up in the main window.
I am using Ubuntu 14.04 x86-64 with Wine 1.7.26.
I forgot to mention that the Notepad++ version I'm currently using is version 6.6.8.
