Probably a bug in pixgridder ?

Hello,
I use pixgridder, a nice plugin, really

But last week-end i download the update
and also the update WP 3.8

Since pix gridder doesn’t work no more 🙁
I found a solution but i am anxious because i don’t like to do this

To make it working I delete this :
CSS pixgridder : z-index: 50 !important;
here : wp-dialog.pix-dialog.pix-page-builder (line 596)

The problem was : The window to edit into a page, into tge grid ,
when i opened it, it was no activ (no clic, nothing = all grey)

Many thanks to tell me if i cans use pixgridder like that ?

Kind regards
bernard
