Icon
The button across the top of the editor are separated into groups by a vertical line (a button I assume) I have done this before but I forget how. What icon (ico or bmp) do you use for this separator?

OI10 easy change (properties)
Other windows render correctly, same control is used in all cases.
I am not using the ControlPart property.
So if you weren't using the ControlPart property and you weren't using an image, how were you achieving the look of a bar? I'm confused about this.
Double check to confirm if it really isn't working or if it is just very light and hard to see. Some versions of Windows will render this very subtly, almost hard to see if you aren't looking closely. Also, make sure to leave enough width (2-3 pixels).
I copied the control from the new working form (using TBD) to the new non-working form (the one that was working) and it doesn't work.
The form that works I can see the control correctly in FORMDES, on the non-working from it is invisible in FORMDES.
BTW I am really confused.
I'm OK with it, do not spend any more time on this I have it working.
Thank you for the help.
The form that was not showing the divider in FORMDES had another picture control overlapping it.
Are you in OI9 or OI10?
