Help! For the past week, when I go to play CC via Facebook on my desktop computer, it opens fine, but there is a black box covering the whole board, so I am unable to click anything to be able to play. Tried 4x over the past week & still happening. Any idea why & how to fix? Or is this a known technical issue/glitch that the game creators need to fix? (if so, how so I let the right people/place know about tit to get it fixed?) Thx!
