Nested JPanels

I have a very large applet that cannot fit onto a browser window so I added a JScrollPane to the JApplet as follows:
getContentPane().add(scrollPane)
To this scroll pane I added a JPanel, lets call it mainPanel, which in turn contains all the other JPanels that make up the JApplet. My problem is that I can move the cursor into the editable fields that appear in the first JPanel under the mainPanel but none of the other JPanels that follow it.
Any help would be appreciated. TIA, Joe

After looking thru the code a little more closely I discovered that the panels were AWT Panels and not Swing JPanels. The documentation clearly states that one should not mix AWT and Swing components together in the same application. After modifying the applet to use only Swing components everything worked out fine.
 
It is sorta covered in the JavaRanch Style Guide.
