With version 2.1 of the SDK you did not need to press ctrl-enter to
move to the next line.  The enter key would move you to the next line
in the editbox.  Is this (ctrl-enter) something new in 3.0?  I have
also been struggling with the MLE trying to get it to behave as it did
with version 2.1 of the SDK.  Can anyone shed some more light on this
subject?  Why has the behavior changed?
