I thought I got rid of that ...darned... thing months ago, but it only stayed away for a few weeks. There are a few things that trigger its coming back. Opening Acrobat 6 is one of them. Sometimes a force quit out of Word means it's there when you start Word again - some little self-healing thing going on.
I'm beginning to think that a macro that runs on opening Word that just closes the toolbar is the way to go.
(Don't you think it's adding insult to injury that when you close the toolbar, the document window doesn't shift upwards?)
