Thanks for that suggestion, I went through and no, no reformatting that is triggered before this is formatted.

I went digging I double checked that my subEditor is created once each time it is used.

It appears that I needed to set the subEditor.Height to something like subEditor.Height := 1; and likewise with subEditor.Width:=1; Now it is working well, not more extra formatting. Thanks again for your help Sergey
