every vocab sounds out zhi1 no matter what the character, marks me wrong then sounds out the correct vocab. this began almost immediately into a 20 minute session. Anybody else?

I get one odd character from time to time sounding wrong, i believe it is a bug on playing the wrong file, however it was different sounds, not the same sound every time nor the same character.

I think these (and several others) are the same bug. I think I know what's happening (one prompt gets stuck in the system and sometimes responds to events that the current prompt should respond to instead), but I've still had no luck figuring out what causes it to start happening. But once it does, it can have several symptoms, including the wrong sounds playing or one pinyin repeatedly showing up in the prompt.

One person suggested it started happening after using the "back" feature, but another said that it happened without any "back". My error reporting so far has proven ineffectual, and I've never been able to reproduce it.

More evidence will be welcome. A page refresh should be able to temporarily fix it.

Nick and team skrit thanks for the quick response. Skritter still makes my Chinese world go 'round.

If I'm not mistaken this happened to me when using a mac. Not a PC?
