# AltGr randomly stops working - Windows 7

My problem is that AltGr just randomly and frequently stops working. I've only seen this problem since the last update (10.1). The only sure way to recover functionality that I've found was to change the keyboard setup (alt+shift). I'm using multiple keyboards on my system so I need to rotate between the languages back to the one I use in Mathematica every time this happens.

I saw Is it possible to get AltGr key to work in Math.exe? but it seems to be on another issue.

I'm running Windows 7.

Considering how I can recover the functionality, I suppose that it might be a Windows issue, but I've not noticed this behavior anywhere else.

EDIT: I just noticed that when AltGr looses it's 'normal' functionality, it activates the menu bar instead.

• Such shortcuts as Alt + "/" etc. work only in English locale. Probably that's the reason for the behavior you observe. Jun 24, 2015 at 10:14
• I'm sorry, but I don't understand what you mean.

• I mean that your keyboard input language should be English in order to have the keyboard shortcuts like Alt+/, Alt+] etc. working. Jun 25, 2015 at 9:01
• It's not a problem of my keyboard input language. In the language I'm using, for example brackets are mapped to the AltGr+Number-keys and it's these combinations that stop working (without me changing language input) since AltGr for some reason starts activating the menu bar in the Mathematica input window.
