Jon Yes, you are absolutely right, it is scary, but on a 6 layer board with some areas needing 50 ohm controlled impedance on both sides of the board for some 2.7 GHz Optical / RF stuff, and the rest of the board being primarily analog using small SO-8 or SOT-23-5 Amplifiers with tons of 0402 discretes packed in with 20 mil clearance part to part, on both sides of the board, and my silkscreen reduced to 25 mil x 5 mil, there sometimes just isn't room to place the cursor in the center of a component when there are several traces and also some reference designators in the way. I generally try to sneak in under the edge of a reference designator on the top layer to get at a component pad on the bottom layer, or to at least get a selection box from which I can choose what I want to select.
As I see it, the way that Murphy's law was implemented in Protel, given 2 objects under the cursor, Protel will always select the one you don't want and if one of the objects is a reference designator and never give you whats under the designator or never give you a box to choose from. In a perfect world this would never happen, but then again . . .

This is scary. I generally click in the center of the component, as I usually do NOT want to edit the pad, but the component. But, sometimes, especially when there is netlist trouble, I click on the pad to see the net name more clearly than the way it is drawn over the pad. Scary to think you can move the pad with a bobble on the mouse button!
