Shuffle layout is one of my favorite features of IW for Acro. However, it seems that it really does not work as expected if Enable Duplex Printing is checked (unless I'm missing something). I have watched several new users struggle with Shuffle only to find success immediately once they uncheck Enable Duplex Printing. If this is the case, maybe it would be best to disable Enable Duplex Printing when Shuffle layout is chosen?
