Bill, thanks for the report. This is an unnamed tab (an artifact of research some time ago) which normally appears at the
right end of the Tab list but somehow has become located at the
left end of the Tab list.
Fortunately, you can control where any Tab appears in the list and whether a Tab is visible or not, using the PP Panel Tab Layout Icon, the 'gear' icon at the right side of each PP Panel.
Click on the PP Panel affected to bring up the Tab Layout Dialog per the screen shot below. Normally, that unnamed Tab resides at the
bottom of the Tab list. If your Dad's is at the top, simply click on the
Order number for that Tab and and enter a number higher than the bottom Tab number, or simply
999. Then click Update. The Tabs will renumber themselves with that unnamed Tab at the bottom. Further (or alternately), you can simply uncheck its
Visible box to make it invisible.
Finally click Update, then Close.
I'll make that little unnamed Tab permanently invisible. Sorry for the confusion. All the best to your Dad!
Ted
