I just updated my mediaelement-and-player.min.js, jquery.js and flashmediaelement.swf to the files currently on github to try to fix a problem I had with IE9. The problem did dissapear, but so did my progressbar and total time. When I look at css with firebug i see:
<span class="mejs-time-total" style="width: 0px;">
Why does this element all of a sudden get a width of 0?? Disabling this gives me back my progressbar. But I can't seem to find a way to be able to do it from my code.
