Attached WinForm has a control named "Currency". When opening the prg file in the code editor, it changes the line
PRIVATE Currency AS System.Windows.Forms.Label
to
PRIVATE CURRENCY AS System.Windows.Forms.Label
so next time it is not possible to open the form in the designer. Prefixing the name with @@ as in
PRIVATE @@Currency AS System.Windows.Forms.Label
did not make the trick, either
