Cant type ALT GR-Key in WoW

Its not possible to write [,], {,}, @ ingame.
It seems ALT GR isnt working when i start my WOW with ISBOXER. When i start standalone wow it works fine

I deleted all my Keymaps, turned off all FTL-Modifiers, Mouse/Keyrepeaters are off and no white & black list enabled.
Then i deleted my WTF-Folder reinstalled Isboxer and created a new profile/charset.
Nothing worked.

Any ideas?

Even this Thread did not solved my Problem:

That thread is for the case where, for example, AltGr+2 would bring up the 2nd window instead of typing @ or whatever it would happen to be for your keyboard layout. That particular issue should no longer be a problem with ISBoxer 38.

If that thread does not solve the problem, I usually just need to know your Region/Language setting in Windows (For your keyboard layout) and I can put out a patch for Inner Space to solve the problem for your language

Its "DE".
But i ask some german boxers and they dont have this problem in wow.
I didnt have this problem 6month ago too (i was inactive)

Even when i change my keyboardlayout to EN/US it did not work.
Same for CTRL+ALT + ...

These are my XML-Files in Innerspace folder:

Okay, AltGr for German in WoW, now fixed in Inner Space build 5377.
