Stormfly, I've just checked your commands_XXX.cfg files for both versions (ACM and GWX). And they both contain the Autoupdate command linked to the 0x3F010017 item from the menu.ini file. That item was remade by OLC to be the new Autoupdate button, on the main layout page. It was also used by Mikhayl in ACM for the same purpose. But in the original GWX (vanilla) interface, that item does something different, not sure what cause I don't have the game installed on this laptop. But whatever it is, whenever Schroeder clicks on that item, the command is given for the autoupdate to switch on/off. Remove all your addons and go to the clean menu_1024_768.ini file and see what item it is.
Schroeder, go to your commands_en.cfg or commands_de.cfg file and find this part:
[Cmd131]
Name=Toggle_TDC_autoupdate
Ctxt=1
MnID=0x3F010017
Key0=0x54,c,"CTRL T"
comment out the MnID line with a semicolon like this:
;MnID=0x3F010017
and you shouldn't have any problem
