Problem with right-clicking

Quite often when right-clicking a point or edge (frequently used for trimming) 3DC does not react to the right click with the menu but seems to ignore it. But unfortunately it inserts a shift in the object layers. Mostly those ‘shifts’ are harmless because all values stay zero but sometimes, maybe with a little movement of the mouse, it sets values that can be quite disturbing. At first sight one is baffled. After a quick glance at the object layers the culprit for the disforming is clear and it’s easy to repair but nevertheless this behavior is quite annoying.
