Hi everyone, thanks for your speedy help! I found un-checking 'continue line drawing' seems to have solved my problem. Some one put a suggestion about un-checking 'use fast feedback' in 'OpenGL', but this seems to have vanished. Does this mean it got moerated out, and I should undo this?
I seem to use lines more often than not to define a point from which to perform the next action, hence my use of un-connected lines (drawing a peculiar tricycle).
Thanks again.
Best regards, Tony J.
