John,
Just a quick follow-up. I needed to edit a few additional labels today. I still couldn't get it to work using Firefox, but when I switched to Chrome it worked great. Thanks for the tip.

Thanks Marcy. I've tried it in Firefox here and can see the problem now. It works OK in Chrome though, so if anyone else is experiencing this problem, please try using the Chrome browser. In the meantime, we'll look into it to see if we can find a fix.
