Actually, I don't know what happened and the bellow window appeared in Mathematica v10 and I can't get rid of this, Although I went to Evaluation Quit Kernel Local, it temporarily disappears but again will be shown which drives me crazy!

Also, however I can't remember, but I think previously, on the top of the Mathematica window the word "Debug" had been not appeared however I continuously I see it.

    $\begingroup$ You need to disable it in the Evaluation menu. Uncheck Evaluation -> Debugger. $\endgroup$ – Szabolcs Sep 16 '15 at 16:08
  • $\begingroup$ No, it is a bug in Mathematica. The Debugger option is already unchecked but this window still appear. The temporary workaround is for every window check and uncheck again the debugger option. However, it will appear again on next start. $\endgroup$ – Louis Yang May 11 '18 at 6:57

Choose Evaluation - Uncheck debugger

If it appears again even after you uncheck, save the program, close MMA and restart. It shouldn't reappear (at-least in my case, seems like its a bug).
