Hi!
 I was trying to intersect two data sets yesterday and today....and it seems like in the dialog box that asks me to enter the names of the 2 datasets that I wish to intersect, the order in which I list the two datasets makes a difference and gives me different number of overlaps. So if I have two datasets A and B if I enter A first and B second in the dialog box, the result is different from if I enter B first and A second in the dialog box. I dont understand how this is possible, since the overlap should not depend on the order of the entries. Am I doing or understanding something wrong?

Any help will be appreciated!
