I have this local debug window that is so annoying

How can I hide it? What is the purpose of it?

This question came from our discussion, support, and feature requests site for users of Mathematica.

Yes, you can. As a general rule, when dealing with frontend questions don't forget to specify your version and platform – Dr. belisarius Jun 14 '12 at 13:32
You can turn it on/off with the menu entry Evaluation > Debugger – Heike Jun 14 '12 at 13:34

## 1. You may turn off this menu selection:

(Or uncheck Debugger to turn off the entire apparatus.)

## 2. The tools are:

### Version 10 bugs

Mathematica 10 (and later) seems to have some strange problems regarding the debugger tools window. In 10.0 and 10.1 under Windows once I turn on the debugger I experience the window persisting even after the menu is unchecked; it reappears when I close a Notebook window. I suspect this has to do with the change to individual window menus rather than a menu bar. Fortunately in my case restarting Mathematica removes the tools window, however other people have experienced it persisting between sessions; see:

What about the second part " What is the purpose of it?":) – Ajasja Jun 14 '12 at 14:21
@Ajasja okay, updated; If you want to present a lecture on the use of a debugger be my guest. :^) – Mr.Wizard Jun 14 '12 at 14:38
didn't work for me :( stoopid thing still there ... any other suggestions? – Solarmew May 14 '15 at 17:38
@Solarmew Are you using version 10? I have experienced weird behavior with the debugger window in 10/10.1. Once it is turned on in a session it seems to keep popping back up even when Debugger is unchecked. However after I restart Mathematica it does not reappear. – Mr.Wizard May 15 '15 at 1:24
I tried restarting it, but it came back XD ... But ctrl+shirt starting it worked :] – Solarmew May 15 '15 at 2:36

In version 10, we need to Evaluation->Quit Kernel and then Start Kernel to prevent the debugger tool window from reappear.

Doesn't toggling Evaluation -> Debugger work? It works for me in 10.0, 10.3 and 10.4. What 10.x version do you have? – Szabolcs Jun 16 at 15:58
No, toggling Evaluation -> Debugger will not prevent the debugger tool window from reappear if you open a new nb file, my version is 10.4.1 and 10.3.1 – Frank Jun 17 at 17:50
Strange, it doesn't happen on my system. Maybe it's time to reset the front end (hold Ctrl-Shift or Command-Shift during startup)? I have the same two versions on OS X. – Szabolcs Jun 17 at 17:56
