While I appreciate the limited adds I grew increasingly frustrated by some unacceptable program flaws. First, there are many circumstances in which it will not allow a “layoff”. Can’t find rhyme or reason but I click the card to lay-off and the program is unresponsive. It will also prohibit rearranging my runs to take greater advantage of a lay off which would result in a lower score for the computer. The last straw came today when the up card would complete a run but I was not able to pick it up. The program forced me to select from the down pile. Ugh.
