Aghhh, this is the piece of information I was missing! Now everything
jumps into the right place, thanks  :-) !
Somehow the information of OPLS scaling the 1-4 interations by 0.5 stucked
so tightly to my mind that I overlooked the fact that defining [pairtypes]
automatically switches off the fudgeLJ option.

Thank you again, Chris, for your explanation and the your time.
Have a nice weekend!
