Actually, I haven't had to make any changes in UserConfig since changing 
it the first time. The edit is always there.

It does not look like that it is seeing the keyboard. Doesn't the 0x01 
flag force keyboard detection?

4.7-RELEASE. The thought of upgrading terrifies me. I can't even figure 
out how to switch keyboards! :-)

I'm waiting for 5.1-RELEASE to be available on CD.
