I'm trying to learn python states and I am building a small tool, so far it looks something like in the screenshot.

I have a problem I stumbled upon accidentally: if hit ' on the keyboard (which apparently is the shortcut for handle detachment) the handle detaches permanently. The tool will not work again, unless I copy the HDA.

I guess I should ask: is there a way to disable detachment for this handle? Or maybe: is there a better way to build this handle in the viewer states, like using a gadget or something (I would like the handle thickness to match the white line)?
