It's been a few weeks, but I had time this past weekend to revisit
this issue.  And I must swallow my pride and say it's got me beat.
Using the code from totalmessage as a base, I worked long and hard
trying to get just one tab working and failed miserably.  As before, I
get no errors in the -jsconcole and using try/catch doesn't return any
errors.  The tree in the tab just never appears.  So this one is going
on the shelf for the forseeable future.  Thanks to all that gave input
into this.  If I ever get it working, I'll post the working code here.

Cheers!
