Please do not multi-post.
You could have cross-posted (as I did here), putting all the groups in the
same message header rather than sending to each group separately. Even that
is somewhat spammish, and given the large overlap in readership in the three
groups to which I'm posting, possibly not very helpful.
But cross-posting is nowhere near as spammish as multi-posting.
I'm afraid I shall decline your offer to try your Swing L&F.
