Hi Bear,

I should have realized better.

I heard a presentation by Steve Riley (MSFT) at a UG recently in which he
outlined security considerations. I was left with a conviction to accept MS
wisdom and ensure patches are applied automatically.

Ok. I've worked it out.

I had protected mode turned on in the Internet Zone and off in the Trusted
Zone.

Turning on Protected Mode for the Trusted zone allowed sites from different
security zones to open in the same window/tab.

Thx.
