Of course you know that this is an “Optical Illusion” –
When you use the /DL it freezes the “tabs” to the left side. and the rest scrolls around. Put some text such as “This is a test of window scrolling” on the left side and on the same line put “XX” on the farthest right sides, and then do /DL 1 with the /WL

And you will see the wrapping effect chop off the left text and move it to the right side. It is simply wrapping the internal Video Buffer.

But we can always use the ‘”games” for fun !!
