Today I had to launch DraftSight 2017 x64 from my computer via Windows Remote Desktop. Upon start, it displayed some message about bad graphics driver, which I ignored, of course, in Remote Desktop the graphics is different than in real computer. The DraftSight performed a bit slower in Remote Desktop, but I managed to do what I wanted to do.

Later I returned physically to my computer, and launched DraftSight normally. Since then, the reponse is terribly slow, zooming and drafting is now unusable. I can find no way to correct it ...

How do I restore the original behavior?
