LC904rc2 Project Browser error?

[Paul Dupuis]

I find that in the project browser under LC904rc2 (Windows 10), I can 
not relayer groups. Button, fields, etc, all relayer fine by drag and 
drop within the hierarchical list of the project browser, but not groups.

Is this a bug or a lack of RTFM on my part to figure out how it is 
supposed to work?

Anyone have a good work around for relayering groups in the IDE under LC904?
