can a staff member take a look at this?
go account -> language settings
change anything, then 'save settings' and i get this;

error
Display name

* Another user is already using that display name

Cheers- neil

I see the problem and have implemented a workaround, then fixed the root cause for the future. You should be good to go. Sorry about that!

all good, thanks nick

strange, but today, each time i refresh the practice page, time starts count from 0. Although, totqal value at progress page is increasing. Also, each time i refresh practice page I lose language settings, they are thrown back to default EN- ZH

Two separate bugs here. I see the issue with the practice page not starting from where you left off, but I have to run to oversee a language lab overflowing with kids practicing on Skritter. I'll see about fixing it after I get back tonight. Don't worry-it's only cosmetic. Your time is being tracked and can be seen on the progress page.

Still haven't tracked down the source language switching one, but I will. Thanks!

Got the first one, with practice time not coming up. While I was at it, I found a way to dramatically speed up load times of the first word to practice. So while I haven't found the source language switching bug, perhaps this speed improvement will whet your appetite.

Found and fixed the source language issue, I think. If you're still on the wrong source language, switch one last time and it should stick.
