This is a more simplified version of the app that reproduces the behavior
I was seeing. Here there is only one panel. Right Click the panel and you
see in the log the event address is the same every time, and it's member
grows with each click.
Still perplexed. Can anyone shed some light on this?
Thanks,
Tim
p.s. also I apologize for the long lines in the code in my last post.
This one should works better.
