I'm afraid that this is the way that the richedit control, as supplied by
Microsoft, works. Once its read-only style is set at creation time, it
cannot be changed during run-time.

One trick to get around this is to use two controls, identical to each other
except the read-only status. When you need to switch to read-only, copy the
current text to the read-only control, hide the read-write control and make
the read-only control visible. When you need to switch back, reverse the
procedure.
