When creating a draggable using the Interface library 1.2 from an HTML element which has some nested elements, some graphical bugs occur during a drag event.
In IE6 some nested elements inside the dragged elements 'disappear' (apparently changing to opacity 0.0)
In IE7 transarent PNG images which are used as background for an HTML element become completely opaque during drag.
Those graphical issues occur after the draggable element has been dragged at least once (during first drag there are no graphical bugs) - I assume that since the iDrag component creates a copy of the dragged element, some properties are not preserved correctly, or not cleared entirely upon drop (leaving residues that are causing the graphical issues during second drag and beyond).
If necessary, I can supply examples of the HTML elements that trigger those graphical issues.
I attached 4 images - Two for each version of Internet Explorer, showing the elemnts before the drag and during second drag (after the element has been dragged once). The graphical issues are obviously more severe in IE6.
