My toolbar includes a Preview Reports menu that attempts to mimic Excel's
Print Preview. The report opens with its own toolbar and sheet tabs hidden.
When preview is closed, the worksheets reappear with sheet tabs visible. So
far so good. Here's the mystery. Sometimes (not always), when preview is
closed and a sheet tab is clicked, the sheet tabs disappear.

Unless my program is haunted, there must be a logical explanation (though I
can't figure it out). Please help if you can. Thank you.
