Swing Combobox Doesn't "Drop Down"

I'm fairly new to Java, so bear with me.

I am creating an applet (using Visual Cafe) and have added a Swing Combobox.

When the applet is run, and I click on the combobox, the list portion doesn't appear.  The Combobox highlights, and with the arrow keys I can cycle through the list, but I need it to drop so that I can select.

or better use normal layout
setLayout(null);  - very bad

Tried that.  It made the combo box bigger, but it still didn't drop down.

The Layout produced an interesting effect.  I tried changing the layout to one of the various default selections that Visual Cafe allows and it completely screwed up the control positions of my applet.  However, the Combobox was still visible, and it did drop down.  So, now the question is, how do I keep the position of all my controls, and have the combo box drop down as well?
Try this out!!!

public void setPopupVisible(boolean v)

public void setPopupVisible(true)
don't mix AWT and Swing components.
extend JApplet instead of java.awt.Applet.
