Hi Michaelk
Thanks for your response - I do have that selected and it does allow me to enter numerical values - my problem is that as soon as any key is pressed, my polar tracking no longer works. And when I hit enter after inputting a numerical value, the numerical value and angle are ignored, and the line is drawn wherever my cursor is at the time.
Incidentally, Vectorworks opened using a different workspace today and the problem disappeared. I then transferred to my regular Workspace and the problem is occurring again. Suggesting there is a setting differently somewhere, I am just unsure where.
