Progress bar is freezing

Hello guys,
I have been using FV Player since September 2015 without any problems. However, I’ve been facing a strange problem lately. All videos play fine, but sometimes the progress bar freezes and becomes unresponsive when I try to move it back and forth, making it impossible for users to move it back to review an explanation, for example. Sometimes refreshing the page makes it work again, sometimes not. I disabled all plugins and the problem still appears. Do you have any idea on how to fix it?
