Hi, I have worked on something similar, and I ended up creating a OpenLayers.Handler.Box outside the OpenLayers.Control.SelectFeature and also call outside the routine "selectBox" from "SelectFeature"
See line 198 in this code: https://github.com/jorix/OL-FeaturePopups/blob/gh-pages/lib/FeaturePopups.js#L198 and "done" callback in line 527. You can test it in: http://jorix.github.com/OL-FeaturePopups/examples/feature-popups.html --press CTRL key while dragging-- Sorry the code has many other things that perhaps prevent you from an easy to read. Feel free to ask.
