FIX:

Upgrade to OpenEdge 10.1C04, 10.2A02 or later. If upgrading to OpenEdge OpenEdge 10.1C04, 10.2A02 or later is not feasible, a workaround is to set the EDITOR widget MODIFIED attribute to true immediately after invoking its READ-FILE() method. For example:
DEFINE VARIABLE cEditor AS CHARACTER NO-UNDO
VIEW-AS EDITOR SIZE 76 BY 10.
DEFINE VARIABLE lOk AS LOGICAL NO-UNDO.
FORM cEditor.
ASSIGN
lOk = cEditor:READ-FILE("C:\OpenEdge\WRK101C\W005140085\OE00180108.p")
cEditor:MODIFIED = TRUE
cEditor.
DISPLAY cEditor.
Another workaround is to ENABLE the EDITOR widget after display DISPLAY editor statement. For example:
DEFINE VARIABLE cEditor AS CHARACTER NO-UNDO
VIEW-AS EDITOR SIZE 76 BY 10.
DEFINE VARIABLE lOk AS LOGICAL NO-UNDO.
FORM cEditor.
ASSIGN
lOk = cEditor:READ-FILE("C:\OpenEdge\WRK101C\W005140085\OE00180108.p")
cEditor.
DISPLAY cEditor.
ENABLE cEditor.
