Using Laserfiche 8.3 Client (have also duplicated with 9.1.1 Client)

In the Client, have set Tools\Options\View\General\Zoom set to "Fit Window".

When first opening a document the page is properly scaled to fit the image pane. Zooming in on the image and then zooming out by double clicking doesn't revert the zoom back to the "Fit Window" setting. It goes to a fit width setting.

Shouldn't the double click revert the zoom back to default? A workaround has been to add a "Fit Window" button to the toolbar, but would prefer not having an extra click.
