Yikes !!!  That's starting to sound really unpleasant for you.
Perhaps a more low-tech approach would be better :)

I think you are working with point features - yes ?  How about just
converting the mouse click to world coordinates and looking for
features that are within a threshold distance (in world units) to that
location.  You could base the threshold on some small fraction of the
currently display map extent.  If you catch more than one feature just
ask the user to zoom in.

Hope this helps
