Focus stuck in INPUT Textfield after hitting enter multiple times

Ok this was just brought to my attention…I have a search input textfield on stage that searches my list component…there is no search button, instead the search is performed 1 second after the user stops typing…(this is done with a key listener)…however the input focus gets stuck in the textfield if you type something (anything) and hit the enter key multiple times…I hit it like 5-10 real quick…then I tried to click my address bar in the browser, and I am unable to type a new URL…it just continues to type in the input text field on screen…any ideas? This doesn’t happen every time…but for the most part the focus gets stuck when you hit enter a few times…
