  1. This doesn't work as it should.
    It works ok for the first thousand - a comma is inserted after entering 1000 - but when you continue entering numbers after that, it inserts consecutive commas after 2 digits, not 3, so you get something like this: 10,00,000 - where it should be: 1,000,000

    Did you test this with more than 4 digits?
