repainting Panels

[Chris Lawson]

Hi,

I am writing a java program using a combinatin of panels ... when the
content of a panel is updated, by calling the repaint() method, the
panel that is repainted gets junk in the background which is an image
of the whole window.

This disappers if there is another repaint (i.e. call the repaint()
manually or the window is resized).

Does anybody know why this occurs and possibly how to fix it?

Thanks
Chris

gives good insights into painting. This sounds suspiciously like an
opacity problem on one or more of the components in the hierarchy.
