Scrollbars

This table shows the supported scrollbars:

Old scrollbar	This scrollbar is inaccurate. The scrollbar slider has a fixed size. It does not reflect the number of records in the session. The slider is at the top, in the middle, or at the bottom of the scrollbar. It does not indicate the relative position in the dataset.
New scrollbar	This scrollbar is more advanced. The size of the scrollbar slider is inversely proportional to the number of records in the session. The position of the slider indicates the relative position in the dataset.

The new scrollbar requires calculation at session startup. Therefore it can affect the performance of a session. The impact on the performance is proportional to the number of records in a session.

To avoid a performance decrease:

• Disable the new scrollbar for sessions that contain many records.
• Disable the new scrollbar for any session, irrespective of the number of records. This is useful for sessions with not so many records, which start slowly.

If you start a session with a disabled scrollbar, the old scrollbar is displayed.
