5.x-1.1 update makes disappear markers

Hello,

I am using Gmap module on a 5.23 Drupal site.
Since I have updated Gmap to 5.x-1.1 version, all the markers have disappear. :(

I have installed the upgrade 5.x-1.1 then flushed all cache, then clicked regenerate in Gmap admin settings: then no markers displayed anymore.

I use Gmap macro to generate maps with markers with custom icons.

-> when I go to /map/macro to build a Gmap Macro: it's allright: I see the markers, all is fine.
But when I paste the Macro in a text field and save, I see the right map but no marker.

And on all old maps associated with dates or text, markers are not displayed anymore...

So, I checked that private download method was not the problem: all is in the right place with the right Permission :
files/js/gmap_markers.js with 664 Permission - as with the old gmap 5.x-1.0 version that I was using before.

I have backed up to this old version 5.x-1.0 and all is fine again : all markers are here again! :)

I think it's a problem related to the rewriting parts of the module code in this 5.x-1.1 update but I have not found where ...

I have tried to compare files to check what is different, with the hope of finding the solution, so if somebody has an idea it would be great.

Thank you
