Display Appearance Problems

There are two rare situations where portions of the underlying display might not be shown correctly while the command line window is shown. The underlying display is not actually changed, and it is shown correctly once the command line window is removed.

The situations are:

  1. The underlying display is a text editor or other display that uses special work station printer mode functions. While the command line window is displayed, the special work station printer mode characters are not shown.
  2. The underlying display is a bidirectional right-to-left display. While the command line window is displayed, the underlying display is flipped and shown from left-to-right.
