I have had this happen to me before and I think I know what happened. If you select a hunt online in the list and then scroll down with the wheel on the mouse without clicking outside of the list first then the wheel will actually move the dot in the list to another hunt selection.
I was pissed when it happend last year as well but we got our cow! Hopefully it works out for you this year. I have learned when doing applications to stay away from the mouse wheel for scrolling.
