Drafsight 64 bit toolbar is gone, how to repair..

I have got it 2 times now, the Draftsight toolbar is suddenly gone.

To repair the toolbars on the 64 bit Debian stretch install :

Open file manager...
Select => show hidden files.

In my case i go to => /home/grotius/.config/ In your case go to => /home/your user name/ .config/

delete folders :
- Dassault Systemes
- dassault-systemes
- Draftsight

Now restart Draftsight. Problem is solved. Good luck...

there is a Reset all Bars to Default under settings
