...states the following:

*Use i: If checked, the calculator is in complex mode and complex solutions will be displayed when they exist. If not checked, the calculator is in real mode and only real solutions will be displayed.

If "Use i" is checked you get complex solutions, so if you try factor(x^2-3x+7) or solve(x^2-3x+7=0) you will get complex solutions.
If you uncheck it factor(x^2-3x+7) will give x^2-3x+7 and solve(x^2-3x+7=0) will give [], no complex solutions are given.
You can still find complex solutions with csolve().

So for me this it the same behavior as described in the help.

What I did not yet fully understand is the CAS "Complex" check box. What does it change if it is checked or not?
