initial	v1

6		Second of all, this may be only a part of solution. I wonder if we shouldn't select widget on mouse down (fired on the drag handle) before the data transfer is created. That would make sure that a selection exists so everything else would work. This is much better solution than just aborting everything. However, I'm not actually able to reproduce such issue manually, what makes a question – are you correct about saying that selection does not exist when we try to get drag range.
