[Known] Mailbox - Stuck Checking Names

1. Title: Mailbox - Stuck Checking Names (comma as input character)
2. Reproduction Rate: 100%
3. Blocker? sort of
4. Details: I know this is a work in progress and may have already been addressed, but you can get stuck 'Checking Names'. You also can't use the ESC key to bring up the options menu, you have to click on the Option icon in the upper right hand corner. I tried a few other non-alphabet characters and they worked as expected. It might only be the comma that is a problem. Since it's stuck checking the name, there isn't a close window button to close the New Mail window. (The close button isn't available while 'Checking Names'.)
5. Steps to Reproduce:
   1. Open a mailbox (I was using the one at a bank)
   2. Click on 'Send Mail'
   3. You now see a list of names.
   4. Pick a name.
   5. Add a comma to the end of the name.
   6. The interface attempts to find the name, of course it can't.
   7. Delete the comma. You should now have a valid name. But it still shows checking name.
   8. It will now stay stuck at this point, continually checking the name.
   9. At this point there isn't any way to close the send window.
   10. You stuck with this window on your screen. The only way to get rid of it is to log out
