Stop cyan guide lines turning dark blue when moved How ?

Hi,

latest Photoshop 26.3

I have always gone with default guideline colours since pshop 4.1....cyan.

now when I move one it goes dark blue and against a dark background, its sort of vanishes.

Someone has meddled, as no one would want that to happen.

week 2 and everyday something else is broken that worked fine in CS6.

Just where do we fix this.

I get the feeling its a UIcolors.txt visit. as I had to, to recreate easy to read rulers.

am I right ?

and just what in there is the name of this pesky happening.,

active guides or something like that.
