Hello from me.

I was just getting used to Libracad, had trouble with entering distances, but got it sussed ok. Quite used to Autocad and Qcad but now on a Chomebook and found Libracad was ok to use. But then I pressed some buttons  and ended up with see image.
Can anyone put me back on the straight and narrow Please ? The lines are my investigation entering lines ok with that its the big black bit that have me baffled, forgot how I got there and can find no way back

Hit Esc-key a few times.

Thanks for the reply, esc did not work, but I have fixed it. The menus had gone to black on black I think, someone had pressed the wrong keys lol
