I don’t know whether the power outage was the cause of
the problem, but that experience with the brief blackout should prompt
you to install an uninterruptible power supply (UPS), which is a
powerful battery linked to your computer. In the event of an outage,
the battery is programmed to kick in immediately, automatically saving
and closing open files and then safely turning off your computer. It
can be set up for a network as well.
As for your Excel problem, it’s likely that somehow a default setting changed. It could have been caused by the power outage or a misplaced click in the Options menu. In any case it’s easy to fix. Click on Tools , Options and then the View tab and add a check in the box next to Windows in Taskbar (see screenshot).
Not only can you now display several files on your screen, but their identifying icons will appear in your desktop’s toolbar as well (see screenshot).
By the way, Word has a similar default. If you suddenly find you can’t display more than one Word file, click on Tools , Options and then the View bar and likewise place a check at Windows in Taskbar .
