Beginner question: Flash8, toolbox, creating a round "hole"

Hi everyone,
I created a rectangle using Rectangle tool. I want a round “hole” at its’ center.
I create a circle using Oval tool, drag it on top of the rectangle and press Delete. Nothing happens. So, how do i create a circle “hole” at the middle of a rectangle ?

I think the simple idea will be fill the selected are with another color might be using brush tool (although it has limited size).

or you can use illustrator to draw the vector object and bring it to flash

Hi Dijup,
Thanks for your response. The problem was solved by creating the 2 shapes at the same layer, mark it all and select “break apart” then selecting the upper shape and delete. Not easy…
