Polar not behaving as expected.

Drawing in Polar mode somehow feels different from what I am used to in AutoCad. I think it might be because the line you are drawing "sways" off from the snap angle and only actually snaps when the second point is placed. In ortho mode the behaviour is as in AutoCad, the line is restricted to right angles. Difficult to describe, but I feel insecure when drawing in polar, because it looks as if I am going to place second point of line at a squint angle.

Anyone else having the same problem? ... or even better, anyone got a solution?
