The background colour of the value in the Single Record View (SRV) changes to Dark Gray if the value is not editable (ie View Only).
But if the value is editable then the background colour changes to White (ie Updateable).
This is for TOAD v10.
In the previous TOAD versions the background colour remained White in all cases in the SRV.
It is possible to do not use such a dark gray colour for non editable columns in the Single Record View?
Waiting for fix in a future release of Toad For Oracle
