How to understand GUI status consistency messages in ATC or Code Inspector

I’ve got the message “Menu bar not created” in the view “ATC Problems” in ADT: There’s no specific description for “Menu bar not created”: The transaction ATC in SAP GUI doesn’t give much information: The link “GUI Usability Check” displays a general documentation (good luck to find out what’s related to “Menu bar not created”): What does this message mean? What to do? Can the message number “STA1-217” be used to find some information?
