During my experiment, participants have to click mouse left button and drag circles while holding button but I have a problem: When I try to drag a circle, cursor speed is much more than stimulus speed and during dragging stimulus stop to follow cursor even though mouse button still clicked. I’ve uploaded a video in order to make clear my problem. I would be grateful for any advice.
PS: There is an invisible circle, that’s the reason of wierd situation (Circle B cannot move left) of Circle B begining 00:13. Please ignore it.
