Hi Eric
Say you want to draw a rectangle.
Select the rectangle tool and start to draw. The command line recognizes that you are drawing a rectangle and displays x1 and y1. But you can't enter any data – it has defaulted to d-mode but the dx box is not on focus. You can't tab from box to box. You also can't change modes – x-mode (x2, y2) to d-mode (dx, dy) or vice-versa.
If you click and leave the rectangle drawn to whatever size it is, you can in fact click the dx box and now enter data – hitting the Enter/return key then draws a second rectangle (or square) the size you entered.
It seems to be the same with all objects.
It isn't working like it did under 4.51
