This is a nice tip. The contestant has said the answer, computerji has locked the answer, but Amitabh says a "BREAK" and pleads you not to go away, leaving you thinking whether the answer was right or wrong?. You now have a shortcut, and i have checked it several times and confirmed. May be you too can see for yourself at the next episode of KBC2 and confirm it. Ok, all BLAH BLAHs apart, lemme document it!
I have highlighted in yellow a block there.
The result of the answer locked appears there.
The cameraman usually shows all the 6 rectangles (or atleast the top 3 rectangles).
The third rectangle of the first row shows the answer.
Watch KBC2, check whether this works, and comment here.
