CA3LE,
I'm certain I have javascript enabled. It must be some other variable that changed since my successful use (Oct 2011) of testmy.net with IE9.
I tried putting testmy.net into my Trusted Zone to get the default "medium" IE9 Internet Option parameter values; still stalled. Then had success using www.speakeasy.net in my Internet Zone, which requires Flash I see, using the same IE9 that stalled on testmy.net.
Thanx for any further insight.
