CRichEditCtrl in OCX - event not fired.

Environment: VC++ 4.2-flat, Win 95

I'm trying to write a Control in which a CRichEditCtrl-derived class is
dynamically created in the Control's OnCreate.

When I try to override my CMyRichEdtCtrl's EN_CHANGE, the event is not
fired. I've also experimented with EN_UPDATE with no success. The event
is not fired at all. (I did use ClassWizard to generate the events. And
my message map I think is OK. It has ON_CONTROL_REFLECT)

But when I override EN_SETFOCUS, the event is fired correctly. I
understand all these messages use Message reflection. But why is
EN_CHANGE not getting fired? Am I doing something fundamentally wrong?
Or have I got my message reflection fundas wrong?

Please upgrade to 4.2b by installing the patch. 4.2-flat is
compatible only with beta versions of operating system 
components, and as such will end up breaking against released
versions of those components.

Have you set the event mask for the control?  You have to send an
EM_SETEVENTMASK or call SetEventMask() on the control and tell
the control to use the ENM_CHANGE mask if you expect to receive
EN_CHANGE notifications.

EN_SETFOCUS isn't affected by the control's mask.

Perhaps it's something fundamental that you're _not_ doing.
