Dell Canvas Pen Dysfunction
I've had pretty consistent issues getting the Dell Canvas and Illustrator to play nice with each other, and it's gotten totally out of control with version 2018. Although some pen functionality has improved, there's one bizarre roadblock... there's a good 7 second delay when selecting objects with the selection tool (which can be cut short by moving the mouse). Using my finger directly on the touch screen works fine, but the pen is almost unusable for this reason.
