Kevin,

Is there a may to provide a visual clue (underline label caption, change label caption color etc) for the Mustkey fields in MM?

If not, I would suggest a character propertyin which a property and value could be entered and run from the container Init.

ie
"This.Label.FontUnderline = .T." or
"This.Label.ForeColor = RGB(255,0,0)

TIA

Rex
