fixed confirmation dialog

Hi to everyone,

i am writing an awt applet. When someone clicks on a button a confirmation dialog pops up. When the user drags(moves) the dialog from it’s inside the drawing panel, the panel contents are erased(destroyed).
Does anyone know how can i make this dialog fixed so that the user couldn’t move it?
Or if it isn’t possible, is there a way to protect my panel’s drawings (lines, circles etc) from being lost?

thanks in advance
thanasis
