Option + drag and shift to contstrain keys not working
The usual function of holding the option key on mac and dragging an object to duplicate has stopped working. In the same way, clicking shift when moving an object or drawing a frame no longer constrains it's dimensions.
Both of these features still work fine in Illustrator (25.1)
The attached video show me trying to draw a square by holding shift when drawing a shape but it doesn't constrain the proportions as it should. It also shows me then trying to duplicate the shape by holding option (mac) and dragging. The cursor changes to suggest that it's working but the shape doesn't duplicate.
This is a BIG problem for productivity as these functions are key to the way I work.
