Recover lost toolbars version 20.6

I have used the Bobcad for drawing for some 20 years. Three days ago I lost the toolbars on the top and left side. Have no idea what I did and can find nothing in my ancient manuals. Any suggestions ?

Same thing happened to me. I used the alt key shortcuts as a work around for a awhile the upgraded to v36. No help from here or BobCad.
Here’s my post search for this
(Missing Menu bar v29)

Turned out it was right under my nose ,in environment under file heading and there they all were. Still not sure what I did to lose them in the first place.
