Trouble making multi entity selection (Sketcher)

[strim]

Trouble making multi entity selection (Sketcher). While holding Ctrl key to select multiple elements in a sketch. Each additional selection is causing previous non constrained elements to move slightly as if I were moving via left click and drag. Even when I'm careful to get on and off the left button quickly? Very small random movement of sketch elements can be very troublesome. Seems I may seen a speed/delay setting somewhere. I would like to continue to have the direct manipulation option.
Insight/opinions ???

Seems to have corrected itself upon restart of Catia.

Do you know about the right clic on a line they use the last option. this will search all elements 'connected' with the line (as long as there is no fork)
