Description of problem:

When more than one key is pressed during Recognition Training mode, application stopps accepting aditional input.

Output of the program:
During practicing the letter 'k' for the third time, I hit letters 'k' and 'j' at the same time. It shouted 'KEY PRESSED EARLY' and and every next key was dismised with 'ignoring key press; too long and probably an interruption'
