I currently have a full install of Fluppy 013 to hard drive. I use the default US English keyboard. After reading this post I decided to switch to the UK English keyboard to see if I could reproduce your issue. I could not. I used the "change country, timezone, keyboard" app in the Control Panel and successfully switched from US English to UK English keyboard. I tested the keyboard. I then successfully switched back to the US English keyboard.
I had hoped to be of some help to you. Unfortunately I am not able to reproduce your issue.
Also this was posted on the Puppeee.com website yesterday:
I am suffering from little bit of information overload and am taking a break to clear my head. I should be back pretty soon.
