In 1.7.0.3 when snapping is turned on the candidates are not shown until something is done to the drawing to force an update such as a click, pan, etc. Likewise when snapping is turned off the same type of update has to be made to force the hiding of the candidates. All other versions this did not require a second trigger to cause the update of the screen. Is this intentional?
I sometimes just toggle snapping using the hotkey " ; " to display the hidden edges of an object. This can't be done any longer.
