Re: Adding a toolbar, stoped JPanel animation

Hi,

I got some advice a few days ago, which solved a dissapearing menubar
problem. But in implementing the solution the original JPanel
animation no longer works. It should start as soon as the toolbar is
created (see main), but the panel remains blank. I've tried using
invokeLater and invokeAndWait, but to no avail. Here's the (now
rather lengthy) code. I've removed the actionListeners code as it's
not relevant. Any ideas would be gratefully read.

Regards,
