[BUG ?] Who can explain to me the CAS options "Use i" and "complex"?

First of all, czeros is not the function to use when you solve an equation, nevertheless it should not provide a wrong answer. as far as I remember the complex home setting allows complex output from real input (solve x^2=-1).
When you enter "assume (z,complex)" first or go to CAS settings and check complex there you will get the correct result czeros( (3+2i)*x+(1-i)*conj(z)=1) will work.
