Position of the Preloader adjusted in CPM.js

Hi there,

I would like to adjust the position of the custom preloader that I specify in Preferences / Start and End.

I checked in the CPM.js and there is a line referring to the preloader. Here is what I can see in the file. No way to adjust the position of the preloader?

It is always close to the bottom border of the screen and I would like to have it in the middle.

Thanks in advance

B
