In the setup.ini file in the Game guru root folder, open in notepad exe while Game guru is shut down and locate this line:
fulldebugview=0
Change to:
fulldebugview=1
Save file and restart Game guru.
This will show the keyboard codes as you press keys.
Please press all the keys that are giving you trouble. If possible would be best to use vid capture while doing this.
This will also allow support to see what the ascii codes are coming from your keyboard.
Mine did not work like your for a long time, then in April we received and update and now my keyboard is fine. (mostly - and + on mine and the raise and lower camera [,],\ controls.)
This should give us a clue as to what is going on.
After recording the video then you can change the statement back in the setup.ini file.
