I have a User who right clicked on the Tollbar and selected:
Customize Toolbar
Multiple rows of buttons if necessary. All buttons will be displayed.
She then decided she didn't like this view so she right clicked on the Toolbar and selected Reset Toolbar.
Her Client did not revert to the original setting of Single row of buttons only.
We restarted etc.

I was able to duplicate this on my Client.

Is this a bug in the GW8SP1 Client or are we missing something.
