Even more curious it's different on the same computer swapping keyboards... Tried it this morning on another computer than mine (did'n't save results, but swapping keyboards really does change the outcome. And they were identical keyboards...?!)
And really curious is a Frysian using an azerty keyboard.
EDIT: typo in the keyboard layout

I had to find out why this was the happening, so I did some research.. it has to do with the number of simultaneous keys you can press on the keyboard, and also where they are.
Not 100% sure I understand why this causes what we are seeing here, but I found this article that explains part of it:
http://www.braille2000.com/brl2000/KeyboardReq.htm
and a quote from someone that took apart their keyboard to figure this one out:
"As I thought, the "problematic" keys occupy a common row. The Left and
Right Shift keys are in the same row but different columns. I suspect
that holding down three or more keys in the same row or column causes
a "lockout". This appears to contravene IBM's PC/AT keyboard spec
which states that "the keyboard is able to detect all keys that are
pressed, and their scan codes will be sent to the interface in correct
sequence, regardless of the number of keys held down".

hmmmm....I think my theory of the invasion of the aliens is much more realistic! ......probably you are one of them and trying to let us see a whole different answer to the problem!! You are trying to manipulate the human being and take over the world!! HA!....I can see this all happen.....mwoehahaha....I'm a genius!!!

The location of my problem keys doesn't seem at all related to the location of my shift keys. There doesn't seem to be any pattern at all.
I still haven't seen a sastifactory explanation for why some keys are fine and some keys don't work.
