[Inkscape-user] Snap problem

This is something I've been meaning to comment of for ages :?

I've been in the habit of grouping objects for schematic components then surrounding them with an invisible bounding box (thinnest possible line with no colour) that is 1mm grid aligned.

This has worked perfectly on older versions of Inkscape so I could quickly and precisely position these objects. However with 0.47 the snap behaviour has become extremely difficult to handle. It seems now that every single point in the object will try to act as a snap focus and accurate positioning is a nightmare :(

Can anyone suggest a way to get bounding box only snapping?
