No. You never say anything about erasing at the old location (in fact, I 
don't know if there is any way to do that). To change the location of an 
object you set its location - and it disappears from the old location 
and appears at the new one. Nothing else needed.

The "grab" command comes with limitations - e.g. the object follows the 
mouse completely - not simply in one dimension as I need, it can only be 
used when the mouseloc is within the object, etc. (according to the docs 
- I've never used it, so can't confirm those).
