As requested by TJ, I'll look into creating a small applet with source
code that can recreate the problem.

When using a Volano chat applet, resizing chat-room windows causes panels to be obscured by the 'background' since it doesn't scale (remains static) and appears in front of the panels.

To reproduce this there is a Volano demo applet at http://www.volano.com/chat.html

Start the chat applet, set "Your Name" and enter any chat 'room'. Resize (enlarge) the resulting Window. The active panels inside the window scale and relocate correctly but the 'background' (some combination of Panel objects possibly) remain in their original positions and obscure the active elements because they are apparently 'in front'.

I wonder if this is a case of an incorrectly inverted draw order of some form, although I doubt it's a common one else other Java applications would exhibit similar issues.

I thought it might be related to bug #282626 "applet window unable to resize" but that is marked 'Fix Released'.

This doesn't affect Sun Java.
