I've noticed that when you blink another indicator the focus is stolen from the typing area. This occurs in 2014 but not 2012. Here's the example:

FYI, I had to use call chain and indexing out controls because I couldn't get snippets to work with front panel references. The string should have keyfocus and allow you to type and the bool should be blinking
