Big Sur issues

FYI I recently built my own tab control that looks almost exactly like the one the Mac displays, but it has two advantages: 

1. It looks good on both Windows AND Mac. 
2. It has support for Drag and Drop. 

You edit the tabs by right-clicking in the “pane” of the group object, then selecting Tabs. You use an answer dialog to enter a comma separated list of tabs. When these are built there are invisible buttons created over the top of the Segmented Control Widget tabs. (The only reason I did this is so I could drag over a button and it would hilite, and also because I could create a behavior that is applied to ALL the buttons, so I only have one place to go to edit the code for them.) 

Sizing works for every side but the top. I haven’t spent any time trying to figure that one out. Also, I’ve had problems adding more than one tab at a time, but I think I know what is wrong there. 

Let me know and I will try to kludge together a sample stack.
