Speaking question problem
Occasionally when I am doing a lesson or practice and I get to the part where I need to speak into my microphone, if I wait some time, switch to another tab, or try enough times unsuccessfully (I am often in a noisy coffee shop and need to repeat myself multiple times), the "record" button stops working or responding. The only way I have found to make it start working again is to reload the page (or skip the question, which of course uses a heart).
I have seen this behaviour intermittently ever since using Duolingo. Sometimes the 'Record' button does not appear and sometimes it appears but does not respond when I click it. I have to click 'Do not know answer' and skip the question and lose a heart. It happens maybe one time in 50 - I can find no pattern to when it will occur. I am using Chrome browser on Windows Vista.
