If you drag the scroll bar to pan the contents of the data frame, the scroll bar jumps back to its previous position until the display stops drawing.
The scroll bars controls don't update in proper sequence with the data display.
Solution or Workaround
- Instead of dragging the scroll bar, click above, below, left, or right of the bar to pan one screen over, or click the arrow buttons at the edges of your scroll bars.
- In data view, click to the left and right of the scroll bar to pan the data.
