Keeping shapes separated on 1 layer

Forgive my ignorence, but how the **** can I draw 2 overlapping shapes of the same color on 1 layer without them being glued together as 1 large shape by Flash??? Also, when I draw a selection rectangle over the shapes to select one or both, how do I get Flah to recognise the original shape & not to take out a piece the size of the selection? MANY THANKS!
