"L" select connected selection tool doesn't work In the below scene, I cannot seem to select the shape on the left by hovering over it and pressing "L" select connected.



In the below screen shot, I pressed L to select other elements of the scene, and all became selected properly:

There is a cursor proximity thereshold in the "Select Linked".

If you are in vertex mode, the cursor must be near a vertex to catch the vertex. It won't work if none of the object's vertices fall into the cursor's radius (e.g. if it is in the middle of a big face)
