Hi Alexandre, > but it would still be nice to nail the cause of the issue.
See: http://jsfiddle.net/jorix/X77cw/ (after returning from a week in the mountains offline... I extracted the code from Canvas.js to set an example of the problem without using OpenLayers) Try "d1" or "d2", so operates properly. But "d1 & d2" not!, the result should be as "d2" (not as d1+d2) :( Regards, Xavier Alexandre Dubé wrote > Xavier, > > You're right. Thanks for sharing your solutions.
