Do you add the control via the resource editor (drag and drop) or are you doing it via code? If not using the editor, try that in a sample app and then see if there are any messages such as your size message sent to the control.

Often when I put an OCX control inside a dialog, the border of the control is not painted correctly. I've seen this quite often, so I thought it's time to find the root cause!
 
The solution has always been to explicitly send a WM_SIZE message (no other trick seems to work):
 
CRect rect;
m_htmlCtrl.GetClientRect(rect);
m_htmlCtrl.SendMessage(WM_SIZE, SIZE_RESTORED, MAKELPARAM(rect.Width(), rect.Height()));
 
I tried to find the underlying problem and found out that the desired rectangle was always decreased by 4 pixels (width and height). Strange.
 
Any ideas? I really dislike the hack above :(
