Which brokerage holds your account? It would be interesting to get that information from those posting on this thread to see how different companies handle this. See also my entry in this thread titled "Don't rejoice quite yet," for more details on how these get handled.
amorganoo, in addition to checking your transactions, might also check your available trading balance and compare it to what it was yesterday. You might find, as I did, that the available trading balance had increased by the exact amount that the dividend is supposed to be. Again, more details on that "Don't rejoice" entry in this thread.
JJJohnson I ask you as well -- which brokerage is your account with?
