Cant get the bagging to work

So I bought this game because I love time management games but how dissapointed I am that when its time for the customer to check out the game seems to freeze and it wont register the placement of the "top" on the bag. I am extremely dissapointed by this because now I cant go any further in the game. The customers get mad and leave so therefore nobody buys anything and low and behold I am stuck on the first level for eternity!!?
