Keyboard oddity, very low priority, very odd behavior

[Harlan Gilbert]

For some reason, when listening to the keyboard, certain keyboard combinations cause an infinite number of key presses to be registered. 

When running the following key-listener:

Web VPython 3.2

writing = label("Character count:")
#scene.bind('keydown', keyInput)
count = 0
while(True):
    rate(10)
    keys =  keysdown()
    for key in keys:
        print(key, end="")
        count+=1
        writing.text = "Character count = "  +  count

Pressing ALT or CTRL + certain characters results in an infinite series of keypresses registered. Sometimes this is an infinite number of ALT/CTRLs, sometimes of the accompanying character

This is triggered by typing ALT/CTRL-s, -d, -f, -j, -k, -l, -b, etc.

SHIFT-(letter) also triggers this for many letters.
