Nav Map Tools

[Maky]

Hi People,

I have been playing Silent Hunter 3 For quite some time with G.W.X and Commander.

I have come across something that is bugging me intensely and stopping me playing on full hardcore settings with no map update which I don't want to do.

When I'm plotting ranges etc on the Nav map the ruler seems to be unaccurate.
let me explain...

If you go to full zoom or most other views in Nav map view, notice the scale in the bottom left corner. in full zoom its 50-100-150-200-250m.
Now when you take out the ruler tool and drag it beside this this scale, what happens?
It dosn't measure properly.
It's always 50m out.
It only correctly points out at 250m 500m 750m 1000m
this is highly frustrating to me and I was wondering if it can be rectified somehow.

Has anyone else noticed this?
I'm guessing not a lot of you play with no map update/god eye disabled.

***update***
I am currently reading a tutorial by wazzoo who notices this annoying problem and states his hope that it is rectified with a patch.
this is a old tutorial so does anyone know of a mod / patch???
