DraftSight 2020 Mac unstability

Hello,

I don't know about you, but I have a lot of problems with the beta 2020 version for MacOs.

I have made a first installation with many problems.

When I opened the app, the window was reduced in the top left corner of the screen, and the window formats was not memorized.

Chamfers and fillets don't work with lines anymore, only with polylines (I don't remember if it worked with the 2019 version...).

There was a G-code generator window that can't be permanently removed. And when I want to remove the add-ins, it crashes...

Etc., etc.

Since I have made a new clean install, some problems have been fixed, the interface is better, but the windows are still not memorized.
Fillets and chamfers now work, but it's still very unstable, for example when I move a polyline heads, the application crashes immediatly.

Does anyone else have the same problems? or is there a new beta announced?

Sincerely.
