TMGR: Scrolling Behavior in a View When Group By Option Select (159390)

SYMPTOMS

You may see the following behavior scrolling through a document when you are using the Group By option for a view:

The sliding bar on the vertical scroll bar may not move when clicking above or below the sliding bar to page up or page down. This may also happen if you are clicking the top or bottom arrow buttons on the vertical scroll bars.
The selected item may change in the view if you are using the sliding bar to scroll through the list. This is most obvious when there are few items in each of the categories of the group.
When dragging the sliding button on the vertical scroll bar, the button only stops at specific point on the scroll bar. It seems you cannot position it at the exact location you want.

CAUSE

When using the Group By option in a view, the scroll range is set to the number of category items in the group. In this case, scrolling does not follow a smooth, linear progression through the document. The sliding button on the scroll bar jumps to discrete locations. Each of these positions matches one of the categories in the group.
