When you open a large data set within SAS Life Science Analytics Framework 5.2.x or 5.3, a problem can occur in which the Page Up or Page Down buttons become unresponsive.

This issue can occur after you scroll through a significant number of rows and then press the Page Up or Page Down buttons multiple times.

If you encounter this issue, a workaround is either to click with your mouse to a different location in the data set, or to scroll using the mouse wheel or scroll bar. This activity should restore the functionality for the Page Up and Page Down buttons.

The issue is addressed in SAS Life Science Analytics Framework 5.4.1.
