How did I change the signature? If I remember correctly (and typed it

You tell me. :) I'm going by the documentation:
CDialog::Createhttp://msdn2.microsoft.com/en-us/library/yhth57kd(VS.80).aspx
<q>
virtual BOOL Create(
LPCTSTR lpszTemplateName,
CWnd* pParentWnd = NULL
);
virtual BOOL Create(
UINT nIDTemplate,
CWnd* pParentWnd = NULL
);
</q>
Did the wizard really create a new function in your derived class named
Create with signature:
BOOL CFooDlg::Create(CWnd * pParent)
{
pCV=(CMyBar *) pParent;
}
Note also that it's bad to overload virtual functions as CDialog does with
Create, but this wasn't too evident 15 years ago when MFC was being
written. Just avoid doing it in new code.

Oh, now that I go actually look at the code... :)
Well, you are quite right.
I have this in several Dialogs, I obviously copied the bad code from
one class to another several times. Now I see that the signature is
not the same as even the base class that the function calls. So I
guess I better go fix them all :-)
Thanks for your help - it's much appreciated.
