Forums mIRC Help Color changes when highlighted....?

I am using mIRC 6.17 and when I highlight a line of text.
If the text is BLUE it becomes YELLOW.
RED becomes TEAL
GREEN becomes PURPLE

It used to only do Black and White which I was fine with, how I can set it back to that ?

u cant, this is a know concern, and maybe it wel be addressed in the next release.

Thanks I guess I cannot do anythign but wait see what happens.
