OFF: Can Only Unhide One Binder Section at a Time

CAUSE

This behavior is by design of Microsoft Office Binder. Although you can hide multiple sections in a Binder at a time (by holding down either the SHIFT key or the CTRL key and clicking the sections), you can unhide only one section at a time. In the Unhide Sections dialog box, you cannot use the CTRL key or the SHIFT key to select multiple sections. You can select only one section at a time, and then choose OK to display the selected section.

Note that this behavior is the same in Binders as it is in Microsoft Excel; in Microsoft Excel, you can hide multiple worksheets at a time, but you can unhide only one worksheet at a time.
