I tried offsetting the frame of the supeview, but to no avail. I feel like I've tried everything, and I can't get it to draw in a new spot. I don't need a fix, I'd just like to hear from Ali or Mike F that this should be possible. I feel like maybe I'm taking the wrong approach and I need to call dragImageForRowsWithIndexes and then draw that image while the user drags. I'm working on a variant of Sketch and trying to add a new graphic class that is a table view. I'm just wondering if there is something the table view is doing when it gets a mouse down event to lock it's cliprect.
Thanks,
Jason
