The solution arrows are too tiny

Zuril:
The first or second time you emailed to me, you mentioned about the solution arrows that you created. THANK YOU!!!
I would to see those solution arrows to be LARGER so that the mouse is easier to click to them. Please make it more convienient to use the mouse.

Thank you for making this website for free for your users.

Ok. I keep in mind your suggestion next time I make changes to that section of applet.
Sometimes I click on the button with the arrow and the move is not executed.
