Problema con audio--ayudame, por favor!

Hola a todos,
I am having significant difficulty with audio playback. Alguien mas tiene este problema?
Gracias,
Laura

I find that if I play back a lot of tracks or hear a lot during "Hear It Say It", the system often gets slower and slower.  It also takes a long time updating points.  I have a hunch that the two are related.  Updating points must consume a lot of resources.

If that's the case, it's probably a problem with the cache. I would try closing and reopening the browser to see if that helps.
 

There is significant improvement between yesterday and today. I also switched from Chrome to Firefox. Everything works great! Gracias por los respruestas!
