I have noticed this as well.
For me, it works fine when my Chrome zoom is at default (CTRL 0), but if I zoom in or out, I can no longer click on the page peel and it no longer animates.
The pagepeel is postioned absolutely;
#pagepeel{
position:absolute;
right:0;
top:0;
z-index:999!important;
}
and is placed inside a header div in my layout so that it aligns to the right of that div.
It shows up fine and in the right location on zoom, but is no longer clickable ..
