I recall someone mentioning the same thing happened to them in 8.5 a little while ago, but I can't find the thread. Perhaps you (or someone else) may have accidentally right-clicked on the
scrollbars and selected the "Horizontal Scrollbar->Always Off"
option?
To fix it:
Go to File->VI Properties (or right-click on the VI icon in the upper-right of the window and select "VI Properties"). Select the "Window Appearance" category from the menu. Either:
- Select the "Default" option.
-OR-
- Click the "Customize" button. Check the boxes that say "Show vertical scroll bar" and "Show horizontal scroll bar".
Tip: When in Edit mode you can "scroll" the panel by holding down the Control and Shift keys. The cursor will change to a hand, and you can drag the panel around.
