I've been trying the Interface Sortables module that requires the Drag and Drop modules and got bugs when I decided to augment the Object prototype.
I've looked at each of the code of those 3 files and realize that there was a loop over the Object properties (maybe indirectly by the jQuery object) and realize that my function were call, whatever name I give it using the Object.prototype augmentation. That was the reason of the crash. I've filter the the result to not call my function name and I do not have those error message in firebug anymore. Is the design of the Interface plugin bad? I don't know for now if ti comes from jQuery or Interface. That was kind of error firebug gave me: jQuery.iDrop.highlighted[i].get is not a function (idrop.js line 168)
