I have an Acer C720 Chromebook with UK keyboard. When entering my EpisodeSync username I couldn't type the @ sign; it showed as ' whatever the shift/caps status.

On UK keyboards @ is ' shifted.

No problem with other apps; just Beyondpod, and as far as I can see just the EpisodeSync username field.

I had to type the username into another app and copy and paste it; this allowed me to log in fine - although EpisodeSync still doesn't actually work, separate thread created.
