X-Plane pop up windows not active/clickable

Hi All

getting frustrated and dont seem to find a solution.

I run 4 screens from 2 display cards and have arranged them 3 at the bottom in n row for a wide view in x-plane
the top (4th) screen is my main Windows screen and used for other non x-plane goodies

when I click on plugins and select ANYTHING, it pops up on screen no2 ( in the middle - bottom ) and also my "main" x-plane screen where I find the menus and from where it starts up initially
BUT

the windows is not "active"  i.e. can not click any button on it, neither close it again
(default x-plane map as an e.g. is ok, as it pops up on screen no 1 - bottom left
if I disable the 1st & 3rd screen and run X-plane on a singe monitor, no problem

I was hoping one can somewhere in a x-plane config file set n default display for pop ups

... any bright ideas ?
