If you look at the capx events, when you position the mouse over a block the opacity turns 50, and when the mouse isn't over, it's 100 opacity.
But when you test it, due to the blocks being next to each other, the opacity never goes back to a 100 if you mouse the mouse to the next block. Try moving the mouse up and down on the blocks to see what I mean.
I'm just wondering if this is a bug or if there is any workaround. Thanks.
