laggy keypad response

[JTByTheSea]

I'm not exactly sure if this is hardware or software. There is a pause on my keystrokes showing on the screen, and it seems to be related to pressing a key multiple times. i.e. xxxxx requires me to pause before it will recognize the next x (x pause x pause x pause). Particularly annoying ( here the double n) when typing words with double letters (these 2 t) and pressing (those to s) the delete key. Hopefully this is coherent...
Thanks,
JT
